Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647736, here are decompositions:

37 + 8647699 = 8647736
79 + 8647657 = 8647736
157 + 8647579 = 8647736
199 + 8647537 = 8647736
277 + 8647459 = 8647736
367 + 8647369 = 8647736
463 + 8647273 = 8647736
607 + 8647129 = 8647736

Showing the first eight; more decompositions exist.
