Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640704, here are decompositions:

3 + 8640701 = 8640704
13 + 8640691 = 8640704
103 + 8640601 = 8640704
151 + 8640553 = 8640704
157 + 8640547 = 8640704
211 + 8640493 = 8640704
223 + 8640481 = 8640704
277 + 8640427 = 8640704

Showing the first eight; more decompositions exist.
