Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631188, here are decompositions:

37 + 8631151 = 8631188
79 + 8631109 = 8631188
151 + 8631037 = 8631188
331 + 8630857 = 8631188
337 + 8630851 = 8631188
367 + 8630821 = 8631188
409 + 8630779 = 8631188
439 + 8630749 = 8631188

Showing the first eight; more decompositions exist.
