Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640716, here are decompositions:

3 + 8640713 = 8640716
13 + 8640703 = 8640716
37 + 8640679 = 8640716
157 + 8640559 = 8640716
163 + 8640553 = 8640716
223 + 8640493 = 8640716
277 + 8640439 = 8640716
307 + 8640409 = 8640716

Showing the first eight; more decompositions exist.
