Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534322, here are decompositions:

139 + 31534183 = 31534322
181 + 31534141 = 31534322
271 + 31534051 = 31534322
373 + 31533949 = 31534322
499 + 31533823 = 31534322
601 + 31533721 = 31534322
661 + 31533661 = 31534322
691 + 31533631 = 31534322

Showing the first eight; more decompositions exist.
