Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583796, here are decompositions:

17 + 31583779 = 31583796
19 + 31583777 = 31583796
43 + 31583753 = 31583796
47 + 31583749 = 31583796
67 + 31583729 = 31583796
103 + 31583693 = 31583796
109 + 31583687 = 31583796
137 + 31583659 = 31583796

Showing the first eight; more decompositions exist.
