Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687956, here are decompositions:

3 + 8687953 = 8687956
83 + 8687873 = 8687956
197 + 8687759 = 8687956
227 + 8687729 = 8687956
257 + 8687699 = 8687956
269 + 8687687 = 8687956
353 + 8687603 = 8687956
443 + 8687513 = 8687956

Showing the first eight; more decompositions exist.
