Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513220, here are decompositions:

  • 17 + 33513203 = 33513220
  • 23 + 33513197 = 33513220
  • 53 + 33513167 = 33513220
  • 113 + 33513107 = 33513220
  • 197 + 33513023 = 33513220
  • 233 + 33512987 = 33513220
  • 281 + 33512939 = 33513220
  • 347 + 33512873 = 33513220

Showing the first eight; more decompositions exist.
