Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600908, here are decompositions:

47 + 31600861 = 31600908
107 + 31600801 = 31600908
109 + 31600799 = 31600908
137 + 31600771 = 31600908
167 + 31600741 = 31600908
191 + 31600717 = 31600908
239 + 31600669 = 31600908
359 + 31600549 = 31600908

Showing the first eight; more decompositions exist.
