Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606934, here are decompositions:

3 + 31606931 = 31606934
31 + 31606903 = 31606934
181 + 31606753 = 31606934
193 + 31606741 = 31606934
223 + 31606711 = 31606934
277 + 31606657 = 31606934
283 + 31606651 = 31606934
397 + 31606537 = 31606934

Showing the first eight; more decompositions exist.
