Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640792, here are decompositions:

5 + 8640787 = 8640792
11 + 8640781 = 8640792
31 + 8640761 = 8640792
53 + 8640739 = 8640792
59 + 8640733 = 8640792
73 + 8640719 = 8640792
79 + 8640713 = 8640792
89 + 8640703 = 8640792

Showing the first eight; more decompositions exist.
