Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609322, here are decompositions:

  • 109 + 31609213 = 31609322
  • 211 + 31609111 = 31609322
  • 229 + 31609093 = 31609322
  • 439 + 31608883 = 31609322
  • 499 + 31608823 = 31609322
  • 601 + 31608721 = 31609322
  • 733 + 31608589 = 31609322
  • 1021 + 31608301 = 31609322

Showing the first eight; more decompositions exist.
