As long as 2 is not one of the primes that you are adding, then I can guarantee that you will get a composite. 2 is the only even Prime number. Any time you add two odd numbers together, you will get an even number (which is not prime). So if you add them in pairs, you will have three even numbers, which added together result in an even number, so it is composite. If you throw in 2 as one of the primes that you're adding, then your result is odd, and I don't know what else to say about your result.

You may mean: 3 and 5 are prime numbers that add up to the composite number of 8
Composite.
Composite.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
Yes it is, the numbers that can add up to 4 are 1, 2 and 4. A prime number is a number that can only go to itself and 1 evenly, composite have atleast 1 other number that goes into it perfectly. (that's what she said)
