Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40736, here are decompositions:

  • 37 + 40699 = 40736
  • 43 + 40693 = 40736
  • 97 + 40639 = 40736
  • 109 + 40627 = 40736
  • 127 + 40609 = 40736
  • 139 + 40597 = 40736
  • 193 + 40543 = 40736
  • 229 + 40507 = 40736

Showing the first eight; more decompositions exist.
