Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640608, here are decompositions:

7 + 8640601 = 8640608
61 + 8640547 = 8640608
127 + 8640481 = 8640608
157 + 8640451 = 8640608
181 + 8640427 = 8640608
199 + 8640409 = 8640608
271 + 8640337 = 8640608
349 + 8640259 = 8640608

Showing the first eight; more decompositions exist.
