Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640226, here are decompositions:

5 + 8640221 = 8640226
29 + 8640197 = 8640226
167 + 8640059 = 8640226
239 + 8639987 = 8640226
317 + 8639909 = 8640226
389 + 8639837 = 8640226
479 + 8639747 = 8640226
563 + 8639663 = 8640226

Showing the first eight; more decompositions exist.
