Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581840, here are decompositions:

  • 3 + 33581837 = 33581840
  • 73 + 33581767 = 33581840
  • 79 + 33581761 = 33581840
  • 163 + 33581677 = 33581840
  • 223 + 33581617 = 33581840
  • 241 + 33581599 = 33581840
  • 349 + 33581491 = 33581840
  • 541 + 33581299 = 33581840

Showing the first eight; more decompositions exist.
