Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33502720, here are decompositions:

  • 3 + 33502717 = 33502720
  • 11 + 33502709 = 33502720
  • 29 + 33502691 = 33502720
  • 47 + 33502673 = 33502720
  • 263 + 33502457 = 33502720
  • 269 + 33502451 = 33502720
  • 281 + 33502439 = 33502720
  • 311 + 33502409 = 33502720

Showing the first eight; more decompositions exist.
