Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533640, here are decompositions:

  • 97 + 33533543 = 33533640
  • 113 + 33533527 = 33533640
  • 149 + 33533491 = 33533640
  • 193 + 33533447 = 33533640
  • 197 + 33533443 = 33533640
  • 233 + 33533407 = 33533640
  • 271 + 33533369 = 33533640
  • 311 + 33533329 = 33533640

Showing the first eight; more decompositions exist.
