Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606944, here are decompositions:

13 + 31606931 = 31606944
41 + 31606903 = 31606944
97 + 31606847 = 31606944
191 + 31606753 = 31606944
233 + 31606711 = 31606944
241 + 31606703 = 31606944
263 + 31606681 = 31606944
277 + 31606667 = 31606944

Showing the first eight; more decompositions exist.
