Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650778, here are decompositions:

109 + 8650669 = 8650778
127 + 8650651 = 8650778
151 + 8650627 = 8650778
181 + 8650597 = 8650778
349 + 8650429 = 8650778
457 + 8650321 = 8650778
691 + 8650087 = 8650778
727 + 8650051 = 8650778

Showing the first eight; more decompositions exist.
