Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595716, here are decompositions:

29 + 31595687 = 31595716
59 + 31595657 = 31595716
149 + 31595567 = 31595716
233 + 31595483 = 31595716
353 + 31595363 = 31595716
443 + 31595273 = 31595716
479 + 31595237 = 31595716
653 + 31595063 = 31595716

Showing the first eight; more decompositions exist.
