But a composite number is a product of more than one prime number, not a
complex number. 5, as a complex number, is composite, because it's the
product of 2+i and 2-i, which are prime.

Nit-picky point; composites are products of more than one irreducibles. The two aren't equivalent in every Ring. (Not that I want to start translating every term from abstract algebra.)
