Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659828, here are decompositions:

17 + 8659811 = 8659828
59 + 8659769 = 8659828
137 + 8659691 = 8659828
197 + 8659631 = 8659828
227 + 8659601 = 8659828
239 + 8659589 = 8659828
269 + 8659559 = 8659828
647 + 8659181 = 8659828

Showing the first eight; more decompositions exist.
