Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631394, here are decompositions:

3 + 8631391 = 8631394
53 + 8631341 = 8631394
227 + 8631167 = 8631394
311 + 8631083 = 8631394
353 + 8631041 = 8631394
383 + 8631011 = 8631394
491 + 8630903 = 8631394
557 + 8630837 = 8631394

Showing the first eight; more decompositions exist.
