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.

Are prime numbers closed under addition?
no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
Are composite numbers closed under addition?
No, they are not. You can add two composite numbers, 15 and 14 for example, and get a sum, 29, that is prime.
