Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584064, here are decompositions:

167 + 31583897 = 31584064
227 + 31583837 = 31584064
233 + 31583831 = 31584064
293 + 31583771 = 31584064
311 + 31583753 = 31584064
401 + 31583663 = 31584064
431 + 31583633 = 31584064
443 + 31583621 = 31584064

Showing the first eight; more decompositions exist.
