Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728272, here are decompositions:

11 + 8728261 = 8728272
31 + 8728241 = 8728272
61 + 8728211 = 8728272
79 + 8728193 = 8728272
103 + 8728169 = 8728272
193 + 8728079 = 8728272
199 + 8728073 = 8728272
283 + 8727989 = 8728272

Showing the first eight; more decompositions exist.
