Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594438, here are decompositions:

17 + 31594421 = 31594438
107 + 31594331 = 31594438
167 + 31594271 = 31594438
191 + 31594247 = 31594438
389 + 31594049 = 31594438
479 + 31593959 = 31594438
569 + 31593869 = 31594438
599 + 31593839 = 31594438

Showing the first eight; more decompositions exist.
