Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594962, here are decompositions:

31 + 31594931 = 31594962
43 + 31594919 = 31594962
59 + 31594903 = 31594962
79 + 31594883 = 31594962
89 + 31594873 = 31594962
101 + 31594861 = 31594962
149 + 31594813 = 31594962
151 + 31594811 = 31594962

Showing the first eight; more decompositions exist.
