Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640076, here are decompositions:

17 + 8640059 = 8640076
59 + 8640017 = 8640076
89 + 8639987 = 8640076
167 + 8639909 = 8640076
173 + 8639903 = 8640076
227 + 8639849 = 8640076
239 + 8639837 = 8640076
257 + 8639819 = 8640076

Showing the first eight; more decompositions exist.
