Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631946, here are decompositions:

3 + 8631943 = 8631946
47 + 8631899 = 8631946
53 + 8631893 = 8631946
233 + 8631713 = 8631946
317 + 8631629 = 8631946
347 + 8631599 = 8631946
467 + 8631479 = 8631946
677 + 8631269 = 8631946

Showing the first eight; more decompositions exist.
