Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631122, here are decompositions:

13 + 8631109 = 8631122
139 + 8630983 = 8631122
151 + 8630971 = 8631122
193 + 8630929 = 8631122
223 + 8630899 = 8631122
271 + 8630851 = 8631122
373 + 8630749 = 8631122
439 + 8630683 = 8631122

Showing the first eight; more decompositions exist.
