In order to get three prime numbers to add up to an even number, one of them will have to be even. The only even prime number is 2.144 - 2 = 142.You need to find 2 prime numbers that can add up to 142. 71 is prime and added to itself will be 142, but that won't give you three different prime numbers.Use a list of prime numbers and subtract each prime that is greater than 71 (fewer than primes less than 71) from 142 to see if the difference is another prime:142 - 73 = 69 (not prime)142 - 79 = 63 (not prime)142 - 83 = 59 (prime)142 - 89 = 53 (prime)142 - 97 = 45 (not prime)142 - 101 = 41 (prime)142 - 103 = 39 (not prime)142 - 107 = 35 (not prime)142 - 109 = 33 (not prime)142 - 113 = 29 (prime)142 - 127 = 15 (not prime)142 - 131 = 11 (prime)142 - 137 = 5 (prime)142 - 139 = 3 (prime)You end up with 7 sets of 3 prime numbers that add up to 144:2, 59, 832, 53, 892, 41, 1012, 29, 1132, 11, 1312, 5, 1372, 3, 139
There are 15 prime numbers up to 50.
The two prime numbers that add up to 19 are 7 and 12. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves. In this case, 7 and 12 are not prime numbers, and there are no two prime numbers that add up to 19.
Prime numbers are infinite.
The two square numbers that add up to 225 are 144+81 = 225
There are several prime numbers that add up to 144 and of it is 71+73 =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.
There is an infinite number of prime numbers after 500!
There are 10 of them. Only the squares of 1 and 11 cannot be made in such a way.
The prime numbers up to 50 are: 2,3,5,7,11,13,17,23,29,31,37,41,43,47.
Prime numbers are those numbers which are only divisible by itself Likewise, 1,3,5,7,11,13,17,19,23,,29,31,37,41,43,47,51,53,57,59. These are the only prime numbers upto 60.
So the composite numbers won't get all bunched up.
2,3,5,7,11,13,17,19,23,29,31,37,39,41,43,47,51,53,57,59,61,67,71,73
There are no prime numbers greater than 10 that add up to 29. Since all prime numbers greater than 2 are odd numbers, no two prime numbers greater than 2 can have an even number for their sum.
Look up a table of prime numbers. All those numbers that are not prime, are composite - except 1, which is neither prime nor composite.
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.
The quoted numbers are all PRIME Numbers. The next prime numbers after '11' are , 13 ,17,19,23,29,31,37,41,43,47, up to '50' Prime Numbers , like ordinary numbers, go to infinity. NB After '2' , there are no. even prime numbers. They are all ODD NUmbers.
