The numbers divisible by 2 are called the even numbers. There is no special name for "all even numbers except 2".

All whole numbers ending with 0 or 5 are divisible by 5 except 0 itself
They are all the numbers that are divisible by 2 with no remainder except 2 itself because it is the only even prime number.
Because everything that ends in an even number is divisible by 2 and everything ending in 5 is divisible by 5. (except 5 itself)
But if a number is divisible only by itself and by 1, then it is prime. So, because all the other even numbers are divisible by themselves, by 1, and by 2, they are all composite (just as all the positive multiples of 3, except 3, itself, are composite).
In contrast, no prime numbers are divisible by 10. Any prime number is divisible only by itself and 1.
