Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728312, here are decompositions:

3 + 8728309 = 8728312
23 + 8728289 = 8728312
71 + 8728241 = 8728312
101 + 8728211 = 8728312
233 + 8728079 = 8728312
239 + 8728073 = 8728312
503 + 8727809 = 8728312
521 + 8727791 = 8728312

Showing the first eight; more decompositions exist.
