Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594322, here are decompositions:

13 + 31594309 = 31594322
163 + 31594159 = 31594322
241 + 31594081 = 31594322
283 + 31594039 = 31594322
379 + 31593943 = 31594322
421 + 31593901 = 31594322
601 + 31593721 = 31594322
619 + 31593703 = 31594322

Showing the first eight; more decompositions exist.
