Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687660, here are decompositions:

19 + 8687641 = 8687660
61 + 8687599 = 8687660
73 + 8687587 = 8687660
139 + 8687521 = 8687660
181 + 8687479 = 8687660
193 + 8687467 = 8687660
199 + 8687461 = 8687660
277 + 8687383 = 8687660

Showing the first eight; more decompositions exist.
