Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12724, here are decompositions:

  • 3 + 12721 = 12724
  • 11 + 12713 = 12724
  • 53 + 12671 = 12724
  • 71 + 12653 = 12724
  • 83 + 12641 = 12724
  • 113 + 12611 = 12724
  • 197 + 12527 = 12724
  • 227 + 12497 = 12724

Showing the first eight; more decompositions exist.
