Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728264, here are decompositions:

3 + 8728261 = 8728264
23 + 8728241 = 8728264
53 + 8728211 = 8728264
71 + 8728193 = 8728264
191 + 8728073 = 8728264
227 + 8728037 = 8728264
491 + 8727773 = 8728264
563 + 8727701 = 8728264

Showing the first eight; more decompositions exist.
