Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640022, here are decompositions:

5 + 8640017 = 8640022
71 + 8639951 = 8640022
101 + 8639921 = 8640022
113 + 8639909 = 8640022
173 + 8639849 = 8640022
269 + 8639753 = 8640022
311 + 8639711 = 8640022
359 + 8639663 = 8640022

Showing the first eight; more decompositions exist.
