Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563322, here are decompositions:

53 + 31563269 = 31563322
101 + 31563221 = 31563322
113 + 31563209 = 31563322
173 + 31563149 = 31563322
191 + 31563131 = 31563322
233 + 31563089 = 31563322
281 + 31563041 = 31563322
293 + 31563029 = 31563322

Showing the first eight; more decompositions exist.
