Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582322, here are decompositions:

  • 3 + 31582319 = 31582322
  • 73 + 31582249 = 31582322
  • 139 + 31582183 = 31582322
  • 151 + 31582171 = 31582322
  • 229 + 31582093 = 31582322
  • 349 + 31581973 = 31582322
  • 433 + 31581889 = 31582322
  • 439 + 31581883 = 31582322

Showing the first eight; more decompositions exist.
