Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707638, here are decompositions:

7 + 8707631 = 8707638
31 + 8707607 = 8707638
47 + 8707591 = 8707638
59 + 8707579 = 8707638
101 + 8707537 = 8707638
281 + 8707357 = 8707638
311 + 8707327 = 8707638
349 + 8707289 = 8707638

Showing the first eight; more decompositions exist.
