Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728966, here are decompositions:

3 + 8728963 = 8728966
23 + 8728943 = 8728966
83 + 8728883 = 8728966
179 + 8728787 = 8728966
317 + 8728649 = 8728966
359 + 8728607 = 8728966
509 + 8728457 = 8728966
569 + 8728397 = 8728966

Showing the first eight; more decompositions exist.
