Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516322, here are decompositions:

3 + 31516319 = 31516322
139 + 31516183 = 31516322
163 + 31516159 = 31516322
193 + 31516129 = 31516322
199 + 31516123 = 31516322
223 + 31516099 = 31516322
241 + 31516081 = 31516322
373 + 31515949 = 31516322

Showing the first eight; more decompositions exist.
