Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595438, here are decompositions:

31 + 31595407 = 31595438
67 + 31595371 = 31595438
229 + 31595209 = 31595438
337 + 31595101 = 31595438
379 + 31595059 = 31595438
439 + 31594999 = 31595438
571 + 31594867 = 31595438
577 + 31594861 = 31595438

Showing the first eight; more decompositions exist.
