Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558322, here are decompositions:

13 + 31558309 = 31558322
193 + 31558129 = 31558322
241 + 31558081 = 31558322
283 + 31558039 = 31558322
619 + 31557703 = 31558322
673 + 31557649 = 31558322
769 + 31557553 = 31558322
811 + 31557511 = 31558322

Showing the first eight; more decompositions exist.
