Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600660, here are decompositions:

31 + 8600629 = 8600660
67 + 8600593 = 8600660
73 + 8600587 = 8600660
127 + 8600533 = 8600660
151 + 8600509 = 8600660
163 + 8600497 = 8600660
193 + 8600467 = 8600660
199 + 8600461 = 8600660

Showing the first eight; more decompositions exist.
