Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584046, here are decompositions:

3 + 31584043 = 31584046
47 + 31583999 = 31584046
149 + 31583897 = 31584046
227 + 31583819 = 31584046
269 + 31583777 = 31584046
293 + 31583753 = 31584046
317 + 31583729 = 31584046
353 + 31583693 = 31584046

Showing the first eight; more decompositions exist.
