Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631118, here are decompositions:

101 + 8631017 = 8631118
107 + 8631011 = 8631118
257 + 8630861 = 8631118
281 + 8630837 = 8631118
347 + 8630771 = 8631118
359 + 8630759 = 8631118
449 + 8630669 = 8631118
479 + 8630639 = 8631118

Showing the first eight; more decompositions exist.
