Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631406, here are decompositions:

5 + 8631401 = 8631406
137 + 8631269 = 8631406
239 + 8631167 = 8631406
383 + 8631023 = 8631406
389 + 8631017 = 8631406
503 + 8630903 = 8631406
569 + 8630837 = 8631406
593 + 8630813 = 8631406

Showing the first eight; more decompositions exist.
