Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647122, here are decompositions:

31 + 8647091 = 8647122
59 + 8647063 = 8647122
61 + 8647061 = 8647122
79 + 8647043 = 8647122
101 + 8647021 = 8647122
151 + 8646971 = 8647122
173 + 8646949 = 8647122
179 + 8646943 = 8647122

Showing the first eight; more decompositions exist.
