Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472400, here are decompositions:

  • 7 + 33472393 = 33472400
  • 37 + 33472363 = 33472400
  • 61 + 33472339 = 33472400
  • 67 + 33472333 = 33472400
  • 163 + 33472237 = 33472400
  • 193 + 33472207 = 33472400
  • 277 + 33472123 = 33472400
  • 421 + 33471979 = 33472400

Showing the first eight; more decompositions exist.
