Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33504840, here are decompositions:

  • 13 + 33504827 = 33504840
  • 23 + 33504817 = 33504840
  • 43 + 33504797 = 33504840
  • 53 + 33504787 = 33504840
  • 137 + 33504703 = 33504840
  • 179 + 33504661 = 33504840
  • 197 + 33504643 = 33504840
  • 199 + 33504641 = 33504840

Showing the first eight; more decompositions exist.
