Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687648, here are decompositions:

7 + 8687641 = 8687648
61 + 8687587 = 8687648
127 + 8687521 = 8687648
181 + 8687467 = 8687648
331 + 8687317 = 8687648
349 + 8687299 = 8687648
421 + 8687227 = 8687648
439 + 8687209 = 8687648

Showing the first eight; more decompositions exist.
