Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631882, here are decompositions:

31 + 8631851 = 8631882
59 + 8631823 = 8631882
79 + 8631803 = 8631882
101 + 8631781 = 8631882
113 + 8631769 = 8631882
139 + 8631743 = 8631882
223 + 8631659 = 8631882
271 + 8631611 = 8631882

Showing the first eight; more decompositions exist.
