Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728832, here are decompositions:

223 + 8728609 = 8728832
241 + 8728591 = 8728832
283 + 8728549 = 8728832
349 + 8728483 = 8728832
523 + 8728309 = 8728832
571 + 8728261 = 8728832
919 + 8727913 = 8728832
1213 + 8727619 = 8728832

Showing the first eight; more decompositions exist.
