Add 2 and 3 (which are both prime) to get 5 (which is prime also). Otherwise, you would always add to an nonprime number. Remember every prime is odd (except 2). Also when two odd numbers are added up, they result in an even number (which is never prime). So the only time when 2 prime numbers add to get a prime number is when the two numbers are 2 and 3.
