I agree that I'm not sure how you're intending to use 'why' here, and I'm pretty sure there's a good answer for any particular meaning.

To answer the question in a possibly unsatisfactory way, 3 is prime because it is a natural number which has exactly two distinct natural number factors, whereas 4 is not prime because it has more than two distinct natural number factors.
