Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728712, here are decompositions:

103 + 8728609 = 8728712
163 + 8728549 = 8728712
199 + 8728513 = 8728712
229 + 8728483 = 8728712
241 + 8728471 = 8728712
331 + 8728381 = 8728712
409 + 8728303 = 8728712
439 + 8728273 = 8728712

Showing the first eight; more decompositions exist.
