Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645908, here are decompositions:

59 + 8645849 = 8645908
149 + 8645759 = 8645908
179 + 8645729 = 8645908
239 + 8645669 = 8645908
251 + 8645657 = 8645908
311 + 8645597 = 8645908
431 + 8645477 = 8645908
641 + 8645267 = 8645908

Showing the first eight; more decompositions exist.
