Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677278, here are decompositions:

11 + 8677267 = 8677278
17 + 8677261 = 8677278
31 + 8677247 = 8677278
97 + 8677181 = 8677278
107 + 8677171 = 8677278
139 + 8677139 = 8677278
151 + 8677127 = 8677278
157 + 8677121 = 8677278

Showing the first eight; more decompositions exist.
