Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574322, here are decompositions:

19 + 31574303 = 31574322
61 + 31574261 = 31574322
89 + 31574233 = 31574322
149 + 31574173 = 31574322
191 + 31574131 = 31574322
223 + 31574099 = 31574322
229 + 31574093 = 31574322
251 + 31574071 = 31574322

Showing the first eight; more decompositions exist.
