There are 10 of them. Only the squares of 1 and 11 cannot be made in such a way.
25 = 23 + 2
Make sure that one of them is 2.
5 and 3 are two prime numbers which on adding give 8.
No, for example you can't create the number 65, which is not a prime number, by adding any two prime numbers.
16 - 9 = 7.
25 = 23 + 2
