Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707628, here are decompositions:

37 + 8707591 = 8707628
151 + 8707477 = 8707628
199 + 8707429 = 8707628
271 + 8707357 = 8707628
277 + 8707351 = 8707628
409 + 8707219 = 8707628
421 + 8707207 = 8707628
439 + 8707189 = 8707628

Showing the first eight; more decompositions exist.
