Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594732, here are decompositions:

3 + 31594729 = 31594732
5 + 31594727 = 31594732
41 + 31594691 = 31594732
149 + 31594583 = 31594732
179 + 31594553 = 31594732
269 + 31594463 = 31594732
311 + 31594421 = 31594732
359 + 31594373 = 31594732

Showing the first eight; more decompositions exist.
