Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631112, here are decompositions:

3 + 8631109 = 8631112
29 + 8631083 = 8631112
71 + 8631041 = 8631112
89 + 8631023 = 8631112
101 + 8631011 = 8631112
251 + 8630861 = 8631112
353 + 8630759 = 8631112
443 + 8630669 = 8631112

Showing the first eight; more decompositions exist.
