Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594486, here are decompositions:

23 + 31594463 = 31594486
113 + 31594373 = 31594486
239 + 31594247 = 31594486
293 + 31594193 = 31594486
353 + 31594133 = 31594486
389 + 31594097 = 31594486
503 + 31593983 = 31594486
617 + 31593869 = 31594486

Showing the first eight; more decompositions exist.
