Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631174, here are decompositions:

7 + 8631167 = 8631174
23 + 8631151 = 8631174
137 + 8631037 = 8631174
151 + 8631023 = 8631174
157 + 8631017 = 8631174
163 + 8631011 = 8631174
173 + 8631001 = 8631174
191 + 8630983 = 8631174

Showing the first eight; more decompositions exist.
