Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583836, here are decompositions:

5 + 31583831 = 31583836
17 + 31583819 = 31583836
59 + 31583777 = 31583836
83 + 31583753 = 31583836
107 + 31583729 = 31583836
149 + 31583687 = 31583836
173 + 31583663 = 31583836
239 + 31583597 = 31583836

Showing the first eight; more decompositions exist.
