Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40816, here are decompositions:

3 + 40813 = 40816
29 + 40787 = 40816
53 + 40763 = 40816
107 + 40709 = 40816
179 + 40637 = 40816
233 + 40583 = 40816
239 + 40577 = 40816
257 + 40559 = 40816

Showing the first eight; more decompositions exist.
