Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583766, here are decompositions:

13 + 31583753 = 31583766
17 + 31583749 = 31583766
37 + 31583729 = 31583766
73 + 31583693 = 31583766
79 + 31583687 = 31583766
103 + 31583663 = 31583766
107 + 31583659 = 31583766
139 + 31583627 = 31583766

Showing the first eight; more decompositions exist.
