Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513120, here are decompositions:

  • 13 + 33513107 = 33513120
  • 19 + 33513101 = 33513120
  • 23 + 33513097 = 33513120
  • 97 + 33513023 = 33513120
  • 181 + 33512939 = 33513120
  • 191 + 33512929 = 33513120
  • 239 + 33512881 = 33513120
  • 281 + 33512839 = 33513120

Showing the first eight; more decompositions exist.
