Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594018, here are decompositions:

59 + 31593959 = 31594018
149 + 31593869 = 31594018
179 + 31593839 = 31594018
251 + 31593767 = 31594018
389 + 31593629 = 31594018
557 + 31593461 = 31594018
641 + 31593377 = 31594018
719 + 31593299 = 31594018

Showing the first eight; more decompositions exist.
