Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594894, here are decompositions:

11 + 31594883 = 31594894
17 + 31594877 = 31594894
83 + 31594811 = 31594894
137 + 31594757 = 31594894
167 + 31594727 = 31594894
281 + 31594613 = 31594894
311 + 31594583 = 31594894
347 + 31594547 = 31594894

Showing the first eight; more decompositions exist.
