Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33680, here are decompositions:

  • 43 + 33637 = 33680
  • 61 + 33619 = 33680
  • 67 + 33613 = 33680
  • 79 + 33601 = 33680
  • 103 + 33577 = 33680
  • 151 + 33529 = 33680
  • 193 + 33487 = 33680
  • 211 + 33469 = 33680

Showing the first eight; more decompositions exist.
