Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594774, here are decompositions:

5 + 31594769 = 31594774
17 + 31594757 = 31594774
47 + 31594727 = 31594774
83 + 31594691 = 31594774
191 + 31594583 = 31594774
227 + 31594547 = 31594774
311 + 31594463 = 31594774
353 + 31594421 = 31594774

Showing the first eight; more decompositions exist.
