Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687918, here are decompositions:

7 + 8687911 = 8687918
37 + 8687881 = 8687918
277 + 8687641 = 8687918
331 + 8687587 = 8687918
397 + 8687521 = 8687918
439 + 8687479 = 8687918
457 + 8687461 = 8687918
601 + 8687317 = 8687918

Showing the first eight; more decompositions exist.
