Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728626, here are decompositions:

17 + 8728609 = 8728626
19 + 8728607 = 8728626
29 + 8728597 = 8728626
47 + 8728579 = 8728626
113 + 8728513 = 8728626
199 + 8728427 = 8728626
229 + 8728397 = 8728626
239 + 8728387 = 8728626

Showing the first eight; more decompositions exist.
