Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475322, here are decompositions:

5 + 31475317 = 31475322
71 + 31475251 = 31475322
79 + 31475243 = 31475322
113 + 31475209 = 31475322
163 + 31475159 = 31475322
181 + 31475141 = 31475322
191 + 31475131 = 31475322
211 + 31475111 = 31475322

Showing the first eight; more decompositions exist.
