Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606222, here are decompositions:

41 + 31606181 = 31606222
173 + 31606049 = 31606222
239 + 31605983 = 31606222
251 + 31605971 = 31606222
269 + 31605953 = 31606222
293 + 31605929 = 31606222
419 + 31605803 = 31606222
443 + 31605779 = 31606222

Showing the first eight; more decompositions exist.
