Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740520, here are decompositions:

  • 3 + 8740517 = 8740520
  • 67 + 8740453 = 8740520
  • 73 + 8740447 = 8740520
  • 109 + 8740411 = 8740520
  • 127 + 8740393 = 8740520
  • 193 + 8740327 = 8740520
  • 199 + 8740321 = 8740520
  • 337 + 8740183 = 8740520

Showing the first eight; more decompositions exist.
