Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605022, here are decompositions:

3 + 31605019 = 31605022
5 + 31605017 = 31605022
89 + 31604933 = 31605022
173 + 31604849 = 31605022
233 + 31604789 = 31605022
263 + 31604759 = 31605022
419 + 31604603 = 31605022
461 + 31604561 = 31605022

Showing the first eight; more decompositions exist.
