Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639086, here are decompositions:

23 + 8639063 = 8639086
59 + 8639027 = 8639086
89 + 8638997 = 8639086
149 + 8638937 = 8639086
233 + 8638853 = 8639086
353 + 8638733 = 8639086
359 + 8638727 = 8639086
389 + 8638697 = 8639086

Showing the first eight; more decompositions exist.
