Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728684, here are decompositions:

5 + 8728679 = 8728684
113 + 8728571 = 8728684
227 + 8728457 = 8728684
257 + 8728427 = 8728684
311 + 8728373 = 8728684
353 + 8728331 = 8728684
443 + 8728241 = 8728684
491 + 8728193 = 8728684

Showing the first eight; more decompositions exist.
