Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594950, here are decompositions:

19 + 31594931 = 31594950
31 + 31594919 = 31594950
43 + 31594907 = 31594950
47 + 31594903 = 31594950
67 + 31594883 = 31594950
73 + 31594877 = 31594950
83 + 31594867 = 31594950
89 + 31594861 = 31594950

Showing the first eight; more decompositions exist.
