Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596342, here are decompositions:

31 + 31596311 = 31596342
149 + 31596193 = 31596342
179 + 31596163 = 31596342
191 + 31596151 = 31596342
199 + 31596143 = 31596342
223 + 31596119 = 31596342
293 + 31596049 = 31596342
313 + 31596029 = 31596342

Showing the first eight; more decompositions exist.
