Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623668, here are decompositions:

  • 17 + 33623651 = 33623668
  • 47 + 33623621 = 33623668
  • 59 + 33623609 = 33623668
  • 149 + 33623519 = 33623668
  • 311 + 33623357 = 33623668
  • 317 + 33623351 = 33623668
  • 467 + 33623201 = 33623668
  • 509 + 33623159 = 33623668

Showing the first eight; more decompositions exist.
