Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640516, here are decompositions:

13 + 8640503 = 8640516
23 + 8640493 = 8640516
89 + 8640427 = 8640516
97 + 8640419 = 8640516
107 + 8640409 = 8640516
109 + 8640407 = 8640516
167 + 8640349 = 8640516
179 + 8640337 = 8640516

Showing the first eight; more decompositions exist.
