Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595858, here are decompositions:

127 + 31595731 = 31595858
139 + 31595719 = 31595858
157 + 31595701 = 31595858
277 + 31595581 = 31595858
487 + 31595371 = 31595858
607 + 31595251 = 31595858
757 + 31595101 = 31595858
859 + 31594999 = 31595858

Showing the first eight; more decompositions exist.
