Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559322, here are decompositions:

5 + 31559317 = 31559322
59 + 31559263 = 31559322
71 + 31559251 = 31559322
83 + 31559239 = 31559322
103 + 31559219 = 31559322
173 + 31559149 = 31559322
191 + 31559131 = 31559322
229 + 31559093 = 31559322

Showing the first eight; more decompositions exist.
