Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595486, here are decompositions:

3 + 31595483 = 31595486
19 + 31595467 = 31595486
79 + 31595407 = 31595486
103 + 31595383 = 31595486
277 + 31595209 = 31595486
313 + 31595173 = 31595486
487 + 31594999 = 31595486
499 + 31594987 = 31595486

Showing the first eight; more decompositions exist.
