Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687756, here are decompositions:

43 + 8687713 = 8687756
97 + 8687659 = 8687756
157 + 8687599 = 8687756
277 + 8687479 = 8687756
373 + 8687383 = 8687756
397 + 8687359 = 8687756
439 + 8687317 = 8687756
457 + 8687299 = 8687756

Showing the first eight; more decompositions exist.
