Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678518, here are decompositions:

11 + 8678507 = 8678518
71 + 8678447 = 8678518
179 + 8678339 = 8678518
281 + 8678237 = 8678518
389 + 8678129 = 8678518
449 + 8678069 = 8678518
461 + 8678057 = 8678518
467 + 8678051 = 8678518

Showing the first eight; more decompositions exist.
