Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530796, here are decompositions:

  • 23 + 31530773 = 31530796
  • 83 + 31530713 = 31530796
  • 113 + 31530683 = 31530796
  • 137 + 31530659 = 31530796
  • 179 + 31530617 = 31530796
  • 317 + 31530479 = 31530796
  • 359 + 31530437 = 31530796
  • 419 + 31530377 = 31530796

Showing the first eight; more decompositions exist.
