Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722724, here are decompositions:

  • 13 + 8722711 = 8722724
  • 103 + 8722621 = 8722724
  • 277 + 8722447 = 8722724
  • 331 + 8722393 = 8722724
  • 421 + 8722303 = 8722724
  • 433 + 8722291 = 8722724
  • 487 + 8722237 = 8722724
  • 601 + 8722123 = 8722724

Showing the first eight; more decompositions exist.
