Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33616812, here are decompositions:

  • 11 + 33616801 = 33616812
  • 59 + 33616753 = 33616812
  • 83 + 33616729 = 33616812
  • 101 + 33616711 = 33616812
  • 193 + 33616619 = 33616812
  • 263 + 33616549 = 33616812
  • 409 + 33616403 = 33616812
  • 419 + 33616393 = 33616812

Showing the first eight; more decompositions exist.
