Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659816, here are decompositions:

5 + 8659811 = 8659816
23 + 8659793 = 8659816
47 + 8659769 = 8659816
149 + 8659667 = 8659816
173 + 8659643 = 8659816
227 + 8659589 = 8659816
257 + 8659559 = 8659816
353 + 8659463 = 8659816

Showing the first eight; more decompositions exist.
