Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612322, here are decompositions:

13 + 31612309 = 31612322
241 + 31612081 = 31612322
439 + 31611883 = 31612322
613 + 31611709 = 31612322
619 + 31611703 = 31612322
739 + 31611583 = 31612322
769 + 31611553 = 31612322
883 + 31611439 = 31612322

Showing the first eight; more decompositions exist.
