Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728736, here are decompositions:

19 + 8728717 = 8728736
73 + 8728663 = 8728736
109 + 8728627 = 8728736
127 + 8728609 = 8728736
139 + 8728597 = 8728736
157 + 8728579 = 8728736
223 + 8728513 = 8728736
349 + 8728387 = 8728736

Showing the first eight; more decompositions exist.
