Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513840, here are decompositions:

  • 29 + 33513811 = 33513840
  • 43 + 33513797 = 33513840
  • 79 + 33513761 = 33513840
  • 109 + 33513731 = 33513840
  • 127 + 33513713 = 33513840
  • 167 + 33513673 = 33513840
  • 179 + 33513661 = 33513840
  • 181 + 33513659 = 33513840

Showing the first eight; more decompositions exist.
