Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631120, here are decompositions:

11 + 8631109 = 8631120
23 + 8631097 = 8631120
37 + 8631083 = 8631120
79 + 8631041 = 8631120
83 + 8631037 = 8631120
97 + 8631023 = 8631120
103 + 8631017 = 8631120
109 + 8631011 = 8631120

Showing the first eight; more decompositions exist.
