Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594936, here are decompositions:

5 + 31594931 = 31594936
17 + 31594919 = 31594936
29 + 31594907 = 31594936
53 + 31594883 = 31594936
59 + 31594877 = 31594936
137 + 31594799 = 31594936
167 + 31594769 = 31594936
179 + 31594757 = 31594936

Showing the first eight; more decompositions exist.
