Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595386, here are decompositions:

3 + 31595383 = 31595386
23 + 31595363 = 31595386
107 + 31595279 = 31595386
113 + 31595273 = 31595386
149 + 31595237 = 31595386
167 + 31595219 = 31595386
197 + 31595189 = 31595386
467 + 31594919 = 31595386

Showing the first eight; more decompositions exist.
