Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631078, here are decompositions:

37 + 8631041 = 8631078
41 + 8631037 = 8631078
61 + 8631017 = 8631078
67 + 8631011 = 8631078
107 + 8630971 = 8631078
149 + 8630929 = 8631078
179 + 8630899 = 8631078
227 + 8630851 = 8631078

Showing the first eight; more decompositions exist.
