Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549322, here are decompositions:

139 + 31549183 = 31549322
223 + 31549099 = 31549322
241 + 31549081 = 31549322
271 + 31549051 = 31549322
283 + 31549039 = 31549322
313 + 31549009 = 31549322
499 + 31548823 = 31549322
709 + 31548613 = 31549322

Showing the first eight; more decompositions exist.
