Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687980, here are decompositions:

17 + 8687963 = 8687980
89 + 8687891 = 8687980
101 + 8687879 = 8687980
107 + 8687873 = 8687980
251 + 8687729 = 8687980
281 + 8687699 = 8687980
293 + 8687687 = 8687980
311 + 8687669 = 8687980

Showing the first eight; more decompositions exist.
