Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687618, here are decompositions:

19 + 8687599 = 8687618
31 + 8687587 = 8687618
97 + 8687521 = 8687618
139 + 8687479 = 8687618
151 + 8687467 = 8687618
157 + 8687461 = 8687618
409 + 8687209 = 8687618
421 + 8687197 = 8687618

Showing the first eight; more decompositions exist.
