Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595948, here are decompositions:

19 + 31595929 = 31595948
67 + 31595881 = 31595948
79 + 31595869 = 31595948
229 + 31595719 = 31595948
277 + 31595671 = 31595948
337 + 31595611 = 31595948
367 + 31595581 = 31595948
379 + 31595569 = 31595948

Showing the first eight; more decompositions exist.
