Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687960, here are decompositions:

7 + 8687953 = 8687960
31 + 8687929 = 8687960
37 + 8687923 = 8687960
79 + 8687881 = 8687960
163 + 8687797 = 8687960
373 + 8687587 = 8687960
439 + 8687521 = 8687960
499 + 8687461 = 8687960

Showing the first eight; more decompositions exist.
