Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677978, here are decompositions:

11 + 8677967 = 8677978
17 + 8677961 = 8677978
131 + 8677847 = 8677978
137 + 8677841 = 8677978
149 + 8677829 = 8677978
251 + 8677727 = 8677978
401 + 8677577 = 8677978
467 + 8677511 = 8677978

Showing the first eight; more decompositions exist.
