Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707640, here are decompositions:

37 + 8707603 = 8707640
61 + 8707579 = 8707640
103 + 8707537 = 8707640
163 + 8707477 = 8707640
211 + 8707429 = 8707640
283 + 8707357 = 8707640
307 + 8707333 = 8707640
313 + 8707327 = 8707640

Showing the first eight; more decompositions exist.
