Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490720, here are decompositions:

  • 83 + 33490637 = 33490720
  • 113 + 33490607 = 33490720
  • 173 + 33490547 = 33490720
  • 191 + 33490529 = 33490720
  • 257 + 33490463 = 33490720
  • 311 + 33490409 = 33490720
  • 359 + 33490361 = 33490720
  • 383 + 33490337 = 33490720

Showing the first eight; more decompositions exist.
