Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527720, here are decompositions:

  • 13 + 33527707 = 33527720
  • 43 + 33527677 = 33527720
  • 67 + 33527653 = 33527720
  • 103 + 33527617 = 33527720
  • 181 + 33527539 = 33527720
  • 277 + 33527443 = 33527720
  • 307 + 33527413 = 33527720
  • 379 + 33527341 = 33527720

Showing the first eight; more decompositions exist.
