Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640746, here are decompositions:

7 + 8640739 = 8640746
13 + 8640733 = 8640746
43 + 8640703 = 8640746
67 + 8640679 = 8640746
193 + 8640553 = 8640746
199 + 8640547 = 8640746
307 + 8640439 = 8640746
337 + 8640409 = 8640746

Showing the first eight; more decompositions exist.
