Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584322, here are decompositions:

23 + 31584299 = 31584322
41 + 31584281 = 31584322
59 + 31584263 = 31584322
89 + 31584233 = 31584322
131 + 31584191 = 31584322
149 + 31584173 = 31584322
179 + 31584143 = 31584322
401 + 31583921 = 31584322

Showing the first eight; more decompositions exist.
