Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583832, here are decompositions:

13 + 31583819 = 31583832
23 + 31583809 = 31583832
29 + 31583803 = 31583832
53 + 31583779 = 31583832
61 + 31583771 = 31583832
79 + 31583753 = 31583832
83 + 31583749 = 31583832
103 + 31583729 = 31583832

Showing the first eight; more decompositions exist.
