Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477140, here are decompositions:

  • 97 + 33477043 = 33477140
  • 163 + 33476977 = 33477140
  • 181 + 33476959 = 33477140
  • 199 + 33476941 = 33477140
  • 211 + 33476929 = 33477140
  • 283 + 33476857 = 33477140
  • 313 + 33476827 = 33477140
  • 331 + 33476809 = 33477140

Showing the first eight; more decompositions exist.
