Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728634, here are decompositions:

7 + 8728627 = 8728634
37 + 8728597 = 8728634
43 + 8728591 = 8728634
151 + 8728483 = 8728634
163 + 8728471 = 8728634
331 + 8728303 = 8728634
373 + 8728261 = 8728634
487 + 8728147 = 8728634

Showing the first eight; more decompositions exist.
