Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646566, here are decompositions:

7 + 8646559 = 8646566
37 + 8646529 = 8646566
79 + 8646487 = 8646566
109 + 8646457 = 8646566
163 + 8646403 = 8646566
307 + 8646259 = 8646566
463 + 8646103 = 8646566
919 + 8645647 = 8646566

Showing the first eight; more decompositions exist.
