Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605222, here are decompositions:

5 + 8605217 = 8605222
11 + 8605211 = 8605222
53 + 8605169 = 8605222
239 + 8604983 = 8605222
359 + 8604863 = 8605222
443 + 8604779 = 8605222
599 + 8604623 = 8605222
683 + 8604539 = 8605222

Showing the first eight; more decompositions exist.
