Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509870, here are decompositions:

  • 67 + 33509803 = 33509870
  • 127 + 33509743 = 33509870
  • 157 + 33509713 = 33509870
  • 211 + 33509659 = 33509870
  • 223 + 33509647 = 33509870
  • 409 + 33509461 = 33509870
  • 547 + 33509323 = 33509870
  • 601 + 33509269 = 33509870

Showing the first eight; more decompositions exist.
