Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680656, here are decompositions:

37 + 8680619 = 8680656
43 + 8680613 = 8680656
73 + 8680583 = 8680656
97 + 8680559 = 8680656
113 + 8680543 = 8680656
239 + 8680417 = 8680656
277 + 8680379 = 8680656
349 + 8680307 = 8680656

Showing the first eight; more decompositions exist.
