What 2 prime numbers add together to make 91?
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
What two prime numbers add up to 144?
Split the number in half and make an equation adding the two together to make the desired amount. Unless the number that is half the total is prime, adjust the first number down by an amount to make it a prime number, then adjust the second one up by an equal amount and check whether it is also a prime number. If the second number is also a prime number, you have found two prime numbers that equal the desired amount. If not, adjust the first number down to another prime number, repeating the procedure above until you have two prime numbers.If you split 144 in half, the result is 72. Take the equation 72 + 72 = 144. Since 71 is prime, adjust the first number down by 1 and the second number up by 1 to get 71 + 73 = 144. Since 73 is prime, too, you now have two prime numbers that add up to 144.
What two prime numbers add up to 247?
The two prime numbers that add up to 247 are 241 and 6. 241 is a prime number because it has only two factors: 1 and 241. However, 6 is not a prime number because it has more than two factors: 1, 2, 3, and 6. When you add 241 and 6 together, you get 247.
What two prime numbers add to make a cube number?
5 and 8
If you add a prime number to itself is the the sum composite or prime?
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
What are the factors of 1920 that add up too 20?
Since 19 is a prime number, it only has two factors - 1 and 19.
If you add two prime numbers together what do you get?
You can get another prime (only if one of the numbers added is 2), for example, 101 + 2 = 103. If you add together two odd prime numbers, you will get an even number, which will not be a prime number. (An even number is a number that is divisible by 2; if such a number is greater than 2, it is not a prime number.)
What even number cannot be formed by two prime numbers?
You can not add two positive prime numbers and get zero.
What 2 prime numbers add to make 1.32?
When you add two or more prime numbers you will only end up with a whole number and not a decimal number.
Does two prime numbers always add up to an even number?
No, they do not. If one of the prime numbers is 2, you will have an odd number.
What 2 prime numbers add together to make 91?
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.

Since 73 is prime, too, you now have two prime numbers that add up to 144.
What 2 prime numbers add up to 27?
29
What two prime numbers add together to make 97?
The only way two prime numbers add up to an odd number is if one of them is 2. Since 95 isn't prime, there is no solution.
What two prime numbers add up to 65?
There's no solution. For two primes to add to an odd number, one of them would have to be two. 63 isn't prime, so there's no solution.
What two prime numbers add up to 247?
The two prime numbers that add up to 247 are 241 and 6. 241 is a prime number because it has only two factors: 1 and 241. However, 6 is not a prime number because it has more than two factors: 1, 2, 3, and 6. When you add 241 and 6 together, you get 247.
