Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676778, here are decompositions:

59 + 8676719 = 8676778
137 + 8676641 = 8676778
191 + 8676587 = 8676778
251 + 8676527 = 8676778
311 + 8676467 = 8676778
347 + 8676431 = 8676778
401 + 8676377 = 8676778
491 + 8676287 = 8676778

Showing the first eight; more decompositions exist.
