Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631928, here are decompositions:

17 + 8631911 = 8631928
29 + 8631899 = 8631928
47 + 8631881 = 8631928
191 + 8631737 = 8631928
269 + 8631659 = 8631928
311 + 8631617 = 8631928
317 + 8631611 = 8631928
359 + 8631569 = 8631928

Showing the first eight; more decompositions exist.
