Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631950, here are decompositions:

7 + 8631943 = 8631950
43 + 8631907 = 8631950
127 + 8631823 = 8631950
163 + 8631787 = 8631950
181 + 8631769 = 8631950
277 + 8631673 = 8631950
433 + 8631517 = 8631950
499 + 8631451 = 8631950

Showing the first eight; more decompositions exist.
