Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728628, here are decompositions:

19 + 8728609 = 8728628
31 + 8728597 = 8728628
37 + 8728591 = 8728628
79 + 8728549 = 8728628
157 + 8728471 = 8728628
241 + 8728387 = 8728628
367 + 8728261 = 8728628
421 + 8728207 = 8728628

Showing the first eight; more decompositions exist.
