Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595398, here are decompositions:

5 + 31595393 = 31595398
11 + 31595387 = 31595398
179 + 31595219 = 31595398
257 + 31595141 = 31595398
389 + 31595009 = 31595398
467 + 31594931 = 31595398
479 + 31594919 = 31595398
491 + 31594907 = 31595398

Showing the first eight; more decompositions exist.
