    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.
