Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547720, here are decompositions:

  • 113 + 33547607 = 33547720
  • 131 + 33547589 = 33547720
  • 137 + 33547583 = 33547720
  • 191 + 33547529 = 33547720
  • 263 + 33547457 = 33547720
  • 347 + 33547373 = 33547720
  • 383 + 33547337 = 33547720
  • 443 + 33547277 = 33547720

Showing the first eight; more decompositions exist.
