Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647616, here are decompositions:

37 + 8647579 = 8647616
79 + 8647537 = 8647616
157 + 8647459 = 8647616
199 + 8647417 = 8647616
223 + 8647393 = 8647616
433 + 8647183 = 8647616
487 + 8647129 = 8647616
673 + 8646943 = 8647616

Showing the first eight; more decompositions exist.
