Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640560, here are decompositions:

7 + 8640553 = 8640560
13 + 8640547 = 8640560
67 + 8640493 = 8640560
79 + 8640481 = 8640560
109 + 8640451 = 8640560
151 + 8640409 = 8640560
211 + 8640349 = 8640560
223 + 8640337 = 8640560

Showing the first eight; more decompositions exist.
