Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594930, here are decompositions:

11 + 31594919 = 31594930
23 + 31594907 = 31594930
47 + 31594883 = 31594930
53 + 31594877 = 31594930
131 + 31594799 = 31594930
173 + 31594757 = 31594930
239 + 31594691 = 31594930
317 + 31594613 = 31594930

Showing the first eight; more decompositions exist.
