Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728630, here are decompositions:

3 + 8728627 = 8728630
23 + 8728607 = 8728630
59 + 8728571 = 8728630
149 + 8728481 = 8728630
173 + 8728457 = 8728630
233 + 8728397 = 8728630
257 + 8728373 = 8728630
389 + 8728241 = 8728630

Showing the first eight; more decompositions exist.
