Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595124, here are decompositions:

23 + 31595101 = 31595124
61 + 31595063 = 31595124
103 + 31595021 = 31595124
137 + 31594987 = 31595124
163 + 31594961 = 31595124
193 + 31594931 = 31595124
241 + 31594883 = 31595124
251 + 31594873 = 31595124

Showing the first eight; more decompositions exist.
