Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716978, here are decompositions:

59 + 8716919 = 8716978
89 + 8716889 = 8716978
251 + 8716727 = 8716978
269 + 8716709 = 8716978
317 + 8716661 = 8716978
359 + 8716619 = 8716978
509 + 8716469 = 8716978
761 + 8716217 = 8716978

Showing the first eight; more decompositions exist.
