Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491020, here are decompositions:

  • 23 + 33490997 = 33491020
  • 29 + 33490991 = 33491020
  • 71 + 33490949 = 33491020
  • 113 + 33490907 = 33491020
  • 131 + 33490889 = 33491020
  • 179 + 33490841 = 33491020
  • 239 + 33490781 = 33491020
  • 257 + 33490763 = 33491020

Showing the first eight; more decompositions exist.
