Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631198, here are decompositions:

5 + 8631193 = 8631198
7 + 8631191 = 8631198
31 + 8631167 = 8631198
47 + 8631151 = 8631198
89 + 8631109 = 8631198
101 + 8631097 = 8631198
157 + 8631041 = 8631198
181 + 8631017 = 8631198

Showing the first eight; more decompositions exist.
