Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533760, here are decompositions:

  • 11 + 33533749 = 33533760
  • 41 + 33533719 = 33533760
  • 97 + 33533663 = 33533760
  • 101 + 33533659 = 33533760
  • 233 + 33533527 = 33533760
  • 263 + 33533497 = 33533760
  • 269 + 33533491 = 33533760
  • 307 + 33533453 = 33533760

Showing the first eight; more decompositions exist.
