Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666836, here are decompositions:

  • 29 + 8666807 = 8666836
  • 53 + 8666783 = 8666836
  • 89 + 8666747 = 8666836
  • 239 + 8666597 = 8666836
  • 293 + 8666543 = 8666836
  • 317 + 8666519 = 8666836
  • 359 + 8666477 = 8666836
  • 419 + 8666417 = 8666836

Showing the first eight; more decompositions exist.
