Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687968, here are decompositions:

5 + 8687963 = 8687968
89 + 8687879 = 8687968
197 + 8687771 = 8687968
239 + 8687729 = 8687968
269 + 8687699 = 8687968
281 + 8687687 = 8687968
491 + 8687477 = 8687968
587 + 8687381 = 8687968

Showing the first eight; more decompositions exist.
