Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687678, here are decompositions:

7 + 8687671 = 8687678
19 + 8687659 = 8687678
37 + 8687641 = 8687678
79 + 8687599 = 8687678
157 + 8687521 = 8687678
199 + 8687479 = 8687678
211 + 8687467 = 8687678
277 + 8687401 = 8687678

Showing the first eight; more decompositions exist.
