Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594966, here are decompositions:

3 + 31594963 = 31594966
5 + 31594961 = 31594966
47 + 31594919 = 31594966
59 + 31594907 = 31594966
83 + 31594883 = 31594966
89 + 31594877 = 31594966
167 + 31594799 = 31594966
197 + 31594769 = 31594966

Showing the first eight; more decompositions exist.
