Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640056, here are decompositions:

43 + 8640013 = 8640056
79 + 8639977 = 8640056
157 + 8639899 = 8640056
193 + 8639863 = 8640056
277 + 8639779 = 8640056
283 + 8639773 = 8640056
307 + 8639749 = 8640056
409 + 8639647 = 8640056

Showing the first eight; more decompositions exist.
