Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631148, here are decompositions:

107 + 8631041 = 8631148
131 + 8631017 = 8631148
137 + 8631011 = 8631148
311 + 8630837 = 8631148
359 + 8630789 = 8631148
389 + 8630759 = 8631148
479 + 8630669 = 8631148
509 + 8630639 = 8631148

Showing the first eight; more decompositions exist.
