if you mean (the saum of two composite integers) yours prof is correct but problem too easy to solve

does not need the prof

you remplace 9 by any composite integer

23 = 15 + (23-15)

but i think the real probelem is with ( the sum of two prime numbre)

Every odd integer > 11 is the sum of two composite integers.

Proof.

Let z be an odd integer > 11.

z - 9 is an even integer > 2.

z - 9 is divisible by 2, with quotient > 1.

z - 9 is composite.

9 = 3 * 3 is composite.

z = 9 + (z - 9) is the sum of two composite integers.
