Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595208, here are decompositions:

19 + 31595189 = 31595208
31 + 31595177 = 31595208
67 + 31595141 = 31595208
107 + 31595101 = 31595208
149 + 31595059 = 31595208
199 + 31595009 = 31595208
277 + 31594931 = 31595208
331 + 31594877 = 31595208

Showing the first eight; more decompositions exist.
