Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609066, here are decompositions:

17 + 31609049 = 31609066
107 + 31608959 = 31609066
113 + 31608953 = 31609066
149 + 31608917 = 31609066
173 + 31608893 = 31609066
179 + 31608887 = 31609066
317 + 31608749 = 31609066
353 + 31608713 = 31609066

Showing the first eight; more decompositions exist.
