Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594366, here are decompositions:

173 + 31594193 = 31594366
233 + 31594133 = 31594366
269 + 31594097 = 31594366
317 + 31594049 = 31594366
383 + 31593983 = 31594366
569 + 31593797 = 31594366
599 + 31593767 = 31594366
647 + 31593719 = 31594366

Showing the first eight; more decompositions exist.
