Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594258, here are decompositions:

11 + 31594247 = 31594258
107 + 31594151 = 31594258
197 + 31594061 = 31594258
389 + 31593869 = 31594258
419 + 31593839 = 31594258
461 + 31593797 = 31594258
491 + 31593767 = 31594258
569 + 31593689 = 31594258

Showing the first eight; more decompositions exist.
