Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595356, here are decompositions:

83 + 31595273 = 31595356
113 + 31595243 = 31595356
137 + 31595219 = 31595356
167 + 31595189 = 31595356
179 + 31595177 = 31595356
293 + 31595063 = 31595356
347 + 31595009 = 31595356
449 + 31594907 = 31595356

Showing the first eight; more decompositions exist.
