Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594618, here are decompositions:

5 + 31594613 = 31594618
71 + 31594547 = 31594618
197 + 31594421 = 31594618
347 + 31594271 = 31594618
467 + 31594151 = 31594618
521 + 31594097 = 31594618
557 + 31594061 = 31594618
569 + 31594049 = 31594618

Showing the first eight; more decompositions exist.
