Only 2. All prime numbers are numbers that have no factors other than themselves and 1. By definition all even numbers are evenly divisible by 2. So any even number higher than 2 has 2 as a factor and therefore is not prime.

2 would be a counterexample to the conjecture that prime numbers are odd. 2 is a prime number but it is the only even prime number.
Prime numbers, except 2, are always odd (they would not be prime if they were even cos they would be divisible by 2.) 1 less than any odd number must be an even number.
No. 14 is an even number and the ONLY even prime is 2.
Yes it can. 2 is an even number and it is prime.
7 is prime and not even.
