Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687708, here are decompositions:

37 + 8687671 = 8687708
67 + 8687641 = 8687708
109 + 8687599 = 8687708
229 + 8687479 = 8687708
241 + 8687467 = 8687708
307 + 8687401 = 8687708
349 + 8687359 = 8687708
409 + 8687299 = 8687708

Showing the first eight; more decompositions exist.
