Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514322, here are decompositions:

13 + 31514309 = 31514322
31 + 31514291 = 31514322
61 + 31514261 = 31514322
83 + 31514239 = 31514322
101 + 31514221 = 31514322
131 + 31514191 = 31514322
163 + 31514159 = 31514322
173 + 31514149 = 31514322

Showing the first eight; more decompositions exist.
