Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677228, here are decompositions:

5 + 8677223 = 8677228
47 + 8677181 = 8677228
89 + 8677139 = 8677228
101 + 8677127 = 8677228
107 + 8677121 = 8677228
149 + 8677079 = 8677228
191 + 8677037 = 8677228
257 + 8676971 = 8677228

Showing the first eight; more decompositions exist.
