Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640536, here are decompositions:

43 + 8640493 = 8640536
97 + 8640439 = 8640536
109 + 8640427 = 8640536
127 + 8640409 = 8640536
199 + 8640337 = 8640536
277 + 8640259 = 8640536
349 + 8640187 = 8640536
367 + 8640169 = 8640536

Showing the first eight; more decompositions exist.
