Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477322, here are decompositions:

31 + 31477291 = 31477322
109 + 31477213 = 31477322
181 + 31477141 = 31477322
211 + 31477111 = 31477322
223 + 31477099 = 31477322
271 + 31477051 = 31477322
523 + 31476799 = 31477322
619 + 31476703 = 31477322

Showing the first eight; more decompositions exist.
