Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707656, here are decompositions:

5 + 8707651 = 8707656
7 + 8707649 = 8707656
53 + 8707603 = 8707656
179 + 8707477 = 8707656
227 + 8707429 = 8707656
263 + 8707393 = 8707656
277 + 8707379 = 8707656
313 + 8707343 = 8707656

Showing the first eight; more decompositions exist.
