Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620966, here are decompositions:

17 + 8620949 = 8620966
23 + 8620943 = 8620966
227 + 8620739 = 8620966
239 + 8620727 = 8620966
293 + 8620673 = 8620966
467 + 8620499 = 8620966
617 + 8620349 = 8620966
659 + 8620307 = 8620966

Showing the first eight; more decompositions exist.
