Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631966, here are decompositions:

23 + 8631943 = 8631966
59 + 8631907 = 8631966
67 + 8631899 = 8631966
73 + 8631893 = 8631966
163 + 8631803 = 8631966
179 + 8631787 = 8631966
197 + 8631769 = 8631966
223 + 8631743 = 8631966

Showing the first eight; more decompositions exist.
