Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631226, here are decompositions:

59 + 8631167 = 8631226
389 + 8630837 = 8631226
467 + 8630759 = 8631226
557 + 8630669 = 8631226
563 + 8630663 = 8631226
587 + 8630639 = 8631226
743 + 8630483 = 8631226
809 + 8630417 = 8631226

Showing the first eight; more decompositions exist.
