Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583950, here are decompositions:

29 + 31583921 = 31583950
53 + 31583897 = 31583950
113 + 31583837 = 31583950
131 + 31583819 = 31583950
173 + 31583777 = 31583950
179 + 31583771 = 31583950
197 + 31583753 = 31583950
257 + 31583693 = 31583950

Showing the first eight; more decompositions exist.
