Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640766, here are decompositions:

5 + 8640761 = 8640766
47 + 8640719 = 8640766
53 + 8640713 = 8640766
59 + 8640707 = 8640766
83 + 8640683 = 8640766
179 + 8640587 = 8640766
263 + 8640503 = 8640766
347 + 8640419 = 8640766

Showing the first eight; more decompositions exist.
