Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595046, here are decompositions:

37 + 31595009 = 31595046
47 + 31594999 = 31595046
59 + 31594987 = 31595046
83 + 31594963 = 31595046
127 + 31594919 = 31595046
139 + 31594907 = 31595046
163 + 31594883 = 31595046
173 + 31594873 = 31595046

Showing the first eight; more decompositions exist.
