Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594756, here are decompositions:

29 + 31594727 = 31594756
173 + 31594583 = 31594756
293 + 31594463 = 31594756
383 + 31594373 = 31594756
509 + 31594247 = 31594756
563 + 31594193 = 31594756
593 + 31594163 = 31594756
659 + 31594097 = 31594756

Showing the first eight; more decompositions exist.
