Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728064, here are decompositions:

127 + 8727937 = 8728064
151 + 8727913 = 8728064
157 + 8727907 = 8728064
193 + 8727871 = 8728064
307 + 8727757 = 8728064
337 + 8727727 = 8728064
421 + 8727643 = 8728064
463 + 8727601 = 8728064

Showing the first eight; more decompositions exist.
