Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477240, here are decompositions:

  • 29 + 33477211 = 33477240
  • 37 + 33477203 = 33477240
  • 79 + 33477161 = 33477240
  • 197 + 33477043 = 33477240
  • 241 + 33476999 = 33477240
  • 263 + 33476977 = 33477240
  • 281 + 33476959 = 33477240
  • 311 + 33476929 = 33477240

Showing the first eight; more decompositions exist.
