Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659918, here are decompositions:

5 + 8659913 = 8659918
107 + 8659811 = 8659918
149 + 8659769 = 8659918
227 + 8659691 = 8659918
251 + 8659667 = 8659918
317 + 8659601 = 8659918
359 + 8659559 = 8659918
461 + 8659457 = 8659918

Showing the first eight; more decompositions exist.
