Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640506, here are decompositions:

3 + 8640503 = 8640506
13 + 8640493 = 8640506
67 + 8640439 = 8640506
79 + 8640427 = 8640506
97 + 8640409 = 8640506
157 + 8640349 = 8640506
337 + 8640169 = 8640506
373 + 8640133 = 8640506

Showing the first eight; more decompositions exist.
