Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584036, here are decompositions:

17 + 31584019 = 31584036
37 + 31583999 = 31584036
47 + 31583989 = 31584036
53 + 31583983 = 31584036
139 + 31583897 = 31584036
173 + 31583863 = 31584036
179 + 31583857 = 31584036
199 + 31583837 = 31584036

Showing the first eight; more decompositions exist.
