Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594974, here are decompositions:

11 + 31594963 = 31594974
13 + 31594961 = 31594974
43 + 31594931 = 31594974
67 + 31594907 = 31594974
71 + 31594903 = 31594974
97 + 31594877 = 31594974
101 + 31594873 = 31594974
107 + 31594867 = 31594974

Showing the first eight; more decompositions exist.
