Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728662, here are decompositions:

13 + 8728649 = 8728662
53 + 8728609 = 8728662
71 + 8728591 = 8728662
83 + 8728579 = 8728662
113 + 8728549 = 8728662
149 + 8728513 = 8728662
179 + 8728483 = 8728662
181 + 8728481 = 8728662

Showing the first eight; more decompositions exist.
