Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631922, here are decompositions:

11 + 8631911 = 8631922
23 + 8631899 = 8631922
29 + 8631893 = 8631922
41 + 8631881 = 8631922
71 + 8631851 = 8631922
179 + 8631743 = 8631922
263 + 8631659 = 8631922
293 + 8631629 = 8631922

Showing the first eight; more decompositions exist.
