Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595962, here are decompositions:

89 + 31595873 = 31595962
131 + 31595831 = 31595962
179 + 31595783 = 31595962
191 + 31595771 = 31595962
239 + 31595723 = 31595962
389 + 31595573 = 31595962
479 + 31595483 = 31595962
569 + 31595393 = 31595962

Showing the first eight; more decompositions exist.
