Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519322, here are decompositions:

181 + 31519141 = 31519322
223 + 31519099 = 31519322
409 + 31518913 = 31519322
463 + 31518859 = 31519322
631 + 31518691 = 31519322
733 + 31518589 = 31519322
1009 + 31518313 = 31519322
1021 + 31518301 = 31519322

Showing the first eight; more decompositions exist.
