The only even number that is prime is 2. the even numbers are 2, 4, 6, 8, etc. Any other even number is also going to be divisible by two., so it won't be prime.

Two is the only even number that is prime. One is the only number that is neither prime nor composite, because to be prime it has to have only two factors. To be composite it needs to have more than two factors.
