Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499840, here are decompositions:

  • 71 + 33499769 = 33499840
  • 83 + 33499757 = 33499840
  • 89 + 33499751 = 33499840
  • 137 + 33499703 = 33499840
  • 149 + 33499691 = 33499840
  • 191 + 33499649 = 33499840
  • 197 + 33499643 = 33499840
  • 239 + 33499601 = 33499840

Showing the first eight; more decompositions exist.
