Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622154, here are decompositions:

17 + 8622137 = 8622154
41 + 8622113 = 8622154
83 + 8622071 = 8622154
113 + 8622041 = 8622154
131 + 8622023 = 8622154
137 + 8622017 = 8622154
227 + 8621927 = 8622154
257 + 8621897 = 8622154

Showing the first eight; more decompositions exist.
