Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583914, here are decompositions:

3 + 31583911 = 31583914
17 + 31583897 = 31583914
83 + 31583831 = 31583914
137 + 31583777 = 31583914
227 + 31583687 = 31583914
251 + 31583663 = 31583914
281 + 31583633 = 31583914
293 + 31583621 = 31583914

Showing the first eight; more decompositions exist.
