Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594986, here are decompositions:

23 + 31594963 = 31594986
67 + 31594919 = 31594986
79 + 31594907 = 31594986
83 + 31594903 = 31594986
103 + 31594883 = 31594986
109 + 31594877 = 31594986
113 + 31594873 = 31594986
173 + 31594813 = 31594986

Showing the first eight; more decompositions exist.
