Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640416, here are decompositions:

7 + 8640409 = 8640416
67 + 8640349 = 8640416
79 + 8640337 = 8640416
157 + 8640259 = 8640416
229 + 8640187 = 8640416
283 + 8640133 = 8640416
307 + 8640109 = 8640416
439 + 8639977 = 8640416

Showing the first eight; more decompositions exist.
