Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33575240, here are decompositions:

  • 7 + 33575233 = 33575240
  • 37 + 33575203 = 33575240
  • 67 + 33575173 = 33575240
  • 103 + 33575137 = 33575240
  • 151 + 33575089 = 33575240
  • 157 + 33575083 = 33575240
  • 373 + 33574867 = 33575240
  • 409 + 33574831 = 33575240

Showing the first eight; more decompositions exist.
