Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631948, here are decompositions:

5 + 8631943 = 8631948
37 + 8631911 = 8631948
41 + 8631907 = 8631948
67 + 8631881 = 8631948
97 + 8631851 = 8631948
167 + 8631781 = 8631948
179 + 8631769 = 8631948
211 + 8631737 = 8631948

Showing the first eight; more decompositions exist.
