Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595488, here are decompositions:

5 + 31595483 = 31595488
101 + 31595387 = 31595488
251 + 31595237 = 31595488
269 + 31595219 = 31595488
311 + 31595177 = 31595488
347 + 31595141 = 31595488
467 + 31595021 = 31595488
479 + 31595009 = 31595488

Showing the first eight; more decompositions exist.
