Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631162, here are decompositions:

11 + 8631151 = 8631162
53 + 8631109 = 8631162
79 + 8631083 = 8631162
139 + 8631023 = 8631162
151 + 8631011 = 8631162
179 + 8630983 = 8631162
191 + 8630971 = 8631162
233 + 8630929 = 8631162

Showing the first eight; more decompositions exist.
