Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546828, here are decompositions:

  • 11 + 31546817 = 31546828
  • 29 + 31546799 = 31546828
  • 107 + 31546721 = 31546828
  • 167 + 31546661 = 31546828
  • 191 + 31546637 = 31546828
  • 227 + 31546601 = 31546828
  • 359 + 31546469 = 31546828
  • 479 + 31546349 = 31546828

Showing the first eight; more decompositions exist.
