Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689786, here are decompositions:

59 + 8689727 = 8689786
113 + 8689673 = 8689786
137 + 8689649 = 8689786
233 + 8689553 = 8689786
257 + 8689529 = 8689786
293 + 8689493 = 8689786
353 + 8689433 = 8689786
467 + 8689319 = 8689786

Showing the first eight; more decompositions exist.
