Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525640, here are decompositions:

  • 47 + 33525593 = 33525640
  • 89 + 33525551 = 33525640
  • 107 + 33525533 = 33525640
  • 149 + 33525491 = 33525640
  • 191 + 33525449 = 33525640
  • 353 + 33525287 = 33525640
  • 359 + 33525281 = 33525640
  • 383 + 33525257 = 33525640

Showing the first eight; more decompositions exist.
