Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595932, here are decompositions:

3 + 31595929 = 31595932
59 + 31595873 = 31595932
101 + 31595831 = 31595932
149 + 31595783 = 31595932
359 + 31595573 = 31595932
449 + 31595483 = 31595932
569 + 31595363 = 31595932
653 + 31595279 = 31595932

Showing the first eight; more decompositions exist.
