Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595566, here are decompositions:

83 + 31595483 = 31595566
173 + 31595393 = 31595566
179 + 31595387 = 31595566
293 + 31595273 = 31595566
347 + 31595219 = 31595566
389 + 31595177 = 31595566
503 + 31595063 = 31595566
557 + 31595009 = 31595566

Showing the first eight; more decompositions exist.
