Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609332, here are decompositions:

43 + 31609289 = 31609332
101 + 31609231 = 31609332
103 + 31609229 = 31609332
109 + 31609223 = 31609332
239 + 31609093 = 31609332
241 + 31609091 = 31609332
283 + 31609049 = 31609332
373 + 31608959 = 31609332

Showing the first eight; more decompositions exist.
