Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640750, here are decompositions:

11 + 8640739 = 8640750
17 + 8640733 = 8640750
31 + 8640719 = 8640750
37 + 8640713 = 8640750
43 + 8640707 = 8640750
47 + 8640703 = 8640750
59 + 8640691 = 8640750
61 + 8640689 = 8640750

Showing the first eight; more decompositions exist.
