Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687716, here are decompositions:

3 + 8687713 = 8687716
17 + 8687699 = 8687716
29 + 8687687 = 8687716
47 + 8687669 = 8687716
113 + 8687603 = 8687716
239 + 8687477 = 8687716
263 + 8687453 = 8687716
293 + 8687423 = 8687716

Showing the first eight; more decompositions exist.
