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.

The sum of two prime numbers will be composite unless one of the prime numbers is 2.
Find the prime factorization. Identify the distinct prime factors. Add them up.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
2. 2 + 3 = 5 Or if you mean like add 3 to the prime number, then add that to the prime? 2 still works!! 2: 2 + 3 = 5. 5 + 2 = 7
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.
It is: 11 because 1+1 = 2 which is the smallest prime number
Composite.
Composite.

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.)

When you add two or more prime numbers you will only end up with a whole number and not a decimal number.
