Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687748, here are decompositions:

19 + 8687729 = 8687748
61 + 8687687 = 8687748
79 + 8687669 = 8687748
89 + 8687659 = 8687748
107 + 8687641 = 8687748
149 + 8687599 = 8687748
227 + 8687521 = 8687748
269 + 8687479 = 8687748

Showing the first eight; more decompositions exist.
