Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595726, here are decompositions:

3 + 31595723 = 31595726
7 + 31595719 = 31595726
73 + 31595653 = 31595726
157 + 31595569 = 31595726
727 + 31594999 = 31595726
739 + 31594987 = 31595726
823 + 31594903 = 31595726
853 + 31594873 = 31595726

Showing the first eight; more decompositions exist.
