Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583956, here are decompositions:

59 + 31583897 = 31583956
137 + 31583819 = 31583956
179 + 31583777 = 31583956
227 + 31583729 = 31583956
263 + 31583693 = 31583956
269 + 31583687 = 31583956
293 + 31583663 = 31583956
359 + 31583597 = 31583956

Showing the first eight; more decompositions exist.
