Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595194, here are decompositions:

5 + 31595189 = 31595194
17 + 31595177 = 31595194
53 + 31595141 = 31595194
131 + 31595063 = 31595194
173 + 31595021 = 31595194
233 + 31594961 = 31595194
263 + 31594931 = 31595194
311 + 31594883 = 31595194

Showing the first eight; more decompositions exist.
