Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631822, here are decompositions:

19 + 8631803 = 8631822
41 + 8631781 = 8631822
53 + 8631769 = 8631822
79 + 8631743 = 8631822
109 + 8631713 = 8631822
149 + 8631673 = 8631822
163 + 8631659 = 8631822
193 + 8631629 = 8631822

Showing the first eight; more decompositions exist.
