Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631382, here are decompositions:

3 + 8631379 = 8631382
41 + 8631341 = 8631382
113 + 8631269 = 8631382
131 + 8631251 = 8631382
191 + 8631191 = 8631382
359 + 8631023 = 8631382
479 + 8630903 = 8631382
521 + 8630861 = 8631382

Showing the first eight; more decompositions exist.
