Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519640, here are decompositions:

  • 17 + 33519623 = 33519640
  • 23 + 33519617 = 33519640
  • 101 + 33519539 = 33519640
  • 113 + 33519527 = 33519640
  • 191 + 33519449 = 33519640
  • 269 + 33519371 = 33519640
  • 311 + 33519329 = 33519640
  • 317 + 33519323 = 33519640

Showing the first eight; more decompositions exist.
