Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594948, here are decompositions:

17 + 31594931 = 31594948
29 + 31594919 = 31594948
41 + 31594907 = 31594948
71 + 31594877 = 31594948
137 + 31594811 = 31594948
149 + 31594799 = 31594948
179 + 31594769 = 31594948
191 + 31594757 = 31594948

Showing the first eight; more decompositions exist.
