Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596220, here are decompositions:

11 + 31596209 = 31596220
101 + 31596119 = 31596220
179 + 31596041 = 31596220
191 + 31596029 = 31596220
251 + 31595969 = 31596220
347 + 31595873 = 31596220
353 + 31595867 = 31596220
389 + 31595831 = 31596220

Showing the first eight; more decompositions exist.
