Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677990, here are decompositions:

11 + 8677979 = 8677990
23 + 8677967 = 8677990
29 + 8677961 = 8677990
107 + 8677883 = 8677990
149 + 8677841 = 8677990
227 + 8677763 = 8677990
263 + 8677727 = 8677990
383 + 8677607 = 8677990

Showing the first eight; more decompositions exist.
