Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506728, here are decompositions:

  • 131 + 33506597 = 33506728
  • 149 + 33506579 = 33506728
  • 179 + 33506549 = 33506728
  • 251 + 33506477 = 33506728
  • 419 + 33506309 = 33506728
  • 461 + 33506267 = 33506728
  • 467 + 33506261 = 33506728
  • 509 + 33506219 = 33506728

Showing the first eight; more decompositions exist.
