Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728616, here are decompositions:

7 + 8728609 = 8728616
19 + 8728597 = 8728616
37 + 8728579 = 8728616
67 + 8728549 = 8728616
103 + 8728513 = 8728616
229 + 8728387 = 8728616
307 + 8728309 = 8728616
313 + 8728303 = 8728616

Showing the first eight; more decompositions exist.
