Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621872, here are decompositions:

  • 13 + 33621859 = 33621872
  • 181 + 33621691 = 33621872
  • 199 + 33621673 = 33621872
  • 211 + 33621661 = 33621872
  • 223 + 33621649 = 33621872
  • 313 + 33621559 = 33621872
  • 331 + 33621541 = 33621872
  • 463 + 33621409 = 33621872

Showing the first eight; more decompositions exist.
