Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595956, here are decompositions:

83 + 31595873 = 31595956
89 + 31595867 = 31595956
149 + 31595807 = 31595956
173 + 31595783 = 31595956
179 + 31595777 = 31595956
233 + 31595723 = 31595956
239 + 31595717 = 31595956
269 + 31595687 = 31595956

Showing the first eight; more decompositions exist.
