Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631124, here are decompositions:

41 + 8631083 = 8631124
83 + 8631041 = 8631124
101 + 8631023 = 8631124
107 + 8631017 = 8631124
113 + 8631011 = 8631124
263 + 8630861 = 8631124
311 + 8630813 = 8631124
353 + 8630771 = 8631124

Showing the first eight; more decompositions exist.
