Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687766, here are decompositions:

7 + 8687759 = 8687766
37 + 8687729 = 8687766
53 + 8687713 = 8687766
67 + 8687699 = 8687766
79 + 8687687 = 8687766
97 + 8687669 = 8687766
107 + 8687659 = 8687766
163 + 8687603 = 8687766

Showing the first eight; more decompositions exist.
