Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600666, here are decompositions:

37 + 8600629 = 8600666
73 + 8600593 = 8600666
79 + 8600587 = 8600666
157 + 8600509 = 8600666
199 + 8600467 = 8600666
229 + 8600437 = 8600666
307 + 8600359 = 8600666
433 + 8600233 = 8600666

Showing the first eight; more decompositions exist.
