Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595464, here are decompositions:

71 + 31595393 = 31595464
101 + 31595363 = 31595464
191 + 31595273 = 31595464
227 + 31595237 = 31595464
401 + 31595063 = 31595464
443 + 31595021 = 31595464
503 + 31594961 = 31595464
557 + 31594907 = 31595464

Showing the first eight; more decompositions exist.
