Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640046, here are decompositions:

29 + 8640017 = 8640046
59 + 8639987 = 8640046
137 + 8639909 = 8640046
197 + 8639849 = 8640046
227 + 8639819 = 8640046
293 + 8639753 = 8640046
383 + 8639663 = 8640046
449 + 8639597 = 8640046

Showing the first eight; more decompositions exist.
