Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700656, here are decompositions:

7 + 8700649 = 8700656
67 + 8700589 = 8700656
109 + 8700547 = 8700656
127 + 8700529 = 8700656
199 + 8700457 = 8700656
373 + 8700283 = 8700656
463 + 8700193 = 8700656
487 + 8700169 = 8700656

Showing the first eight; more decompositions exist.
