Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619640, here are decompositions:

  • 13 + 33619627 = 33619640
  • 37 + 33619603 = 33619640
  • 79 + 33619561 = 33619640
  • 199 + 33619441 = 33619640
  • 349 + 33619291 = 33619640
  • 421 + 33619219 = 33619640
  • 463 + 33619177 = 33619640
  • 487 + 33619153 = 33619640

Showing the first eight; more decompositions exist.
