Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631144, here are decompositions:

47 + 8631097 = 8631144
61 + 8631083 = 8631144
103 + 8631041 = 8631144
107 + 8631037 = 8631144
127 + 8631017 = 8631144
173 + 8630971 = 8631144
241 + 8630903 = 8631144
283 + 8630861 = 8631144

Showing the first eight; more decompositions exist.
