no!

the only prime which is even is the number 2, all other primes are odd

If we add 3 to an odd number we get an even number.

e.g. 7 + 3 = 10

n and n+3

If n is even (not prime), n+3 is odd

If N is odd, n+3 is even (not prime)

2 is the only even prime number, all bigger ones are divisible by 2.
