Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728682, here are decompositions:

3 + 8728679 = 8728682
19 + 8728663 = 8728682
73 + 8728609 = 8728682
103 + 8728579 = 8728682
199 + 8728483 = 8728682
211 + 8728471 = 8728682
373 + 8728309 = 8728682
379 + 8728303 = 8728682

Showing the first eight; more decompositions exist.
