Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594834, here are decompositions:

23 + 31594811 = 31594834
107 + 31594727 = 31594834
251 + 31594583 = 31594834
281 + 31594553 = 31594834
461 + 31594373 = 31594834
503 + 31594331 = 31594834
563 + 31594271 = 31594834
587 + 31594247 = 31594834

Showing the first eight; more decompositions exist.
