Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631962, here are decompositions:

19 + 8631943 = 8631962
139 + 8631823 = 8631962
181 + 8631781 = 8631962
193 + 8631769 = 8631962
463 + 8631499 = 8631962
571 + 8631391 = 8631962
631 + 8631331 = 8631962
643 + 8631319 = 8631962

Showing the first eight; more decompositions exist.
