Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677778, here are decompositions:

7 + 8677771 = 8677778
19 + 8677759 = 8677778
97 + 8677681 = 8677778
127 + 8677651 = 8677778
379 + 8677399 = 8677778
607 + 8677171 = 8677778
727 + 8677051 = 8677778
751 + 8677027 = 8677778

Showing the first eight; more decompositions exist.
