Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640798, here are decompositions:

11 + 8640787 = 8640798
17 + 8640781 = 8640798
31 + 8640767 = 8640798
37 + 8640761 = 8640798
59 + 8640739 = 8640798
79 + 8640719 = 8640798
97 + 8640701 = 8640798
107 + 8640691 = 8640798

Showing the first eight; more decompositions exist.
