Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677378, here are decompositions:

11 + 8677367 = 8677378
89 + 8677289 = 8677378
131 + 8677247 = 8677378
197 + 8677181 = 8677378
239 + 8677139 = 8677378
251 + 8677127 = 8677378
257 + 8677121 = 8677378
557 + 8676821 = 8677378

Showing the first eight; more decompositions exist.
