Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584022, here are decompositions:

3 + 31584019 = 31584022
23 + 31583999 = 31584022
101 + 31583921 = 31584022
191 + 31583831 = 31584022
251 + 31583771 = 31584022
269 + 31583753 = 31584022
293 + 31583729 = 31584022
359 + 31583663 = 31584022

Showing the first eight; more decompositions exist.
