Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477840, here are decompositions:

  • 23 + 33477817 = 33477840
  • 47 + 33477793 = 33477840
  • 127 + 33477713 = 33477840
  • 157 + 33477683 = 33477840
  • 181 + 33477659 = 33477840
  • 191 + 33477649 = 33477840
  • 197 + 33477643 = 33477840
  • 241 + 33477599 = 33477840

Showing the first eight; more decompositions exist.
