Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594944, here are decompositions:

13 + 31594931 = 31594944
37 + 31594907 = 31594944
41 + 31594903 = 31594944
61 + 31594883 = 31594944
67 + 31594877 = 31594944
71 + 31594873 = 31594944
83 + 31594861 = 31594944
131 + 31594813 = 31594944

Showing the first eight; more decompositions exist.
