Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558720, here are decompositions:

  • 29 + 33558691 = 33558720
  • 31 + 33558689 = 33558720
  • 43 + 33558677 = 33558720
  • 47 + 33558673 = 33558720
  • 61 + 33558659 = 33558720
  • 71 + 33558649 = 33558720
  • 131 + 33558589 = 33558720
  • 199 + 33558521 = 33558720

Showing the first eight; more decompositions exist.
