Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728256, here are decompositions:

109 + 8728147 = 8728256
127 + 8728129 = 8728256
349 + 8727907 = 8728256
499 + 8727757 = 8728256
613 + 8727643 = 8728256
673 + 8727583 = 8728256
727 + 8727529 = 8728256
829 + 8727427 = 8728256

Showing the first eight; more decompositions exist.
