Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501572, here are decompositions:

  • 79 + 33501493 = 33501572
  • 271 + 33501301 = 33501572
  • 283 + 33501289 = 33501572
  • 409 + 33501163 = 33501572
  • 499 + 33501073 = 33501572
  • 571 + 33501001 = 33501572
  • 619 + 33500953 = 33501572
  • 661 + 33500911 = 33501572

Showing the first eight; more decompositions exist.
