Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687916, here are decompositions:

5 + 8687911 = 8687916
37 + 8687879 = 8687916
43 + 8687873 = 8687916
89 + 8687827 = 8687916
157 + 8687759 = 8687916
229 + 8687687 = 8687916
257 + 8687659 = 8687916
313 + 8687603 = 8687916

Showing the first eight; more decompositions exist.
