Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606022, here are decompositions:

109 + 31605913 = 31606022
199 + 31605823 = 31606022
211 + 31605811 = 31606022
241 + 31605781 = 31606022
439 + 31605583 = 31606022
661 + 31605361 = 31606022
673 + 31605349 = 31606022
751 + 31605271 = 31606022

Showing the first eight; more decompositions exist.
