Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509928, here are decompositions:

  • 7 + 33509921 = 33509928
  • 37 + 33509891 = 33509928
  • 107 + 33509821 = 33509928
  • 269 + 33509659 = 33509928
  • 281 + 33509647 = 33509928
  • 311 + 33509617 = 33509928
  • 359 + 33509569 = 33509928
  • 367 + 33509561 = 33509928

Showing the first eight; more decompositions exist.
