Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659658, here are decompositions:

31 + 8659627 = 8659658
127 + 8659531 = 8659658
157 + 8659501 = 8659658
277 + 8659381 = 8659658
307 + 8659351 = 8659658
349 + 8659309 = 8659658
379 + 8659279 = 8659658
439 + 8659219 = 8659658

Showing the first eight; more decompositions exist.
