Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640456, here are decompositions:

5 + 8640451 = 8640456
17 + 8640439 = 8640456
29 + 8640427 = 8640456
37 + 8640419 = 8640456
47 + 8640409 = 8640456
107 + 8640349 = 8640456
127 + 8640329 = 8640456
193 + 8640263 = 8640456

Showing the first eight; more decompositions exist.
