Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640822, here are decompositions:

5 + 8640817 = 8640822
23 + 8640799 = 8640822
41 + 8640781 = 8640822
61 + 8640761 = 8640822
83 + 8640739 = 8640822
89 + 8640733 = 8640822
103 + 8640719 = 8640822
109 + 8640713 = 8640822

Showing the first eight; more decompositions exist.
