Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646512, here are decompositions:

109 + 8646403 = 8646512
151 + 8646361 = 8646512
331 + 8646181 = 8646512
349 + 8646163 = 8646512
409 + 8646103 = 8646512
541 + 8645971 = 8646512
571 + 8645941 = 8646512
613 + 8645899 = 8646512

Showing the first eight; more decompositions exist.
