Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605946, here are decompositions:

17 + 31605929 = 31605946
137 + 31605809 = 31605946
167 + 31605779 = 31605946
173 + 31605773 = 31605946
227 + 31605719 = 31605946
233 + 31605713 = 31605946
257 + 31605689 = 31605946
353 + 31605593 = 31605946

Showing the first eight; more decompositions exist.
