Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450006, here are decompositions:

  • 17 + 31449989 = 31450006
  • 83 + 31449923 = 31450006
  • 239 + 31449767 = 31450006
  • 317 + 31449689 = 31450006
  • 359 + 31449647 = 31450006
  • 449 + 31449557 = 31450006
  • 479 + 31449527 = 31450006
  • 557 + 31449449 = 31450006

Showing the first eight; more decompositions exist.
