Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501560, here are decompositions:

  • 67 + 33501493 = 33501560
  • 73 + 33501487 = 33501560
  • 193 + 33501367 = 33501560
  • 241 + 33501319 = 33501560
  • 271 + 33501289 = 33501560
  • 307 + 33501253 = 33501560
  • 373 + 33501187 = 33501560
  • 397 + 33501163 = 33501560

Showing the first eight; more decompositions exist.
