Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687770, here are decompositions:

11 + 8687759 = 8687770
41 + 8687729 = 8687770
71 + 8687699 = 8687770
83 + 8687687 = 8687770
101 + 8687669 = 8687770
167 + 8687603 = 8687770
257 + 8687513 = 8687770
293 + 8687477 = 8687770

Showing the first eight; more decompositions exist.
