Well, honey, let me break it down for you. The sum of two prime numbers can definitely be composite. Take 2 and 3 for example - both prime, but when you add them together, you get 5, which is still prime. But toss in 2 and 4, both prime, and you get 6, which is as composite as it gets. So, yes, the sum of two prime numbers can absolutely be composite.

ProfessorOh, dude, let me drop some knowledge on you. The sum of two prime numbers can totally be composite. Like, imagine adding 3 and 5, which are both prime, you get 8, which is composite. So, yeah, it's totally possible. Cool, right?

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.
Is the sum of any two prime numbers always a composite number?
The sum of any two prime numbers is not always a composite number. The sum of 2 and 11 is 13, and 13 is a prime number, not a composite number.
When adding 2 prime number will the answer be prime?
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.
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.
Is the sum of two composite numbers also composite?
Not always as for example 20+9 = 29 which is a prime number
