Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667724, here are decompositions:

  • 3 + 8667721 = 8667724
  • 17 + 8667707 = 8667724
  • 47 + 8667677 = 8667724
  • 71 + 8667653 = 8667724
  • 83 + 8667641 = 8667724
  • 113 + 8667611 = 8667724
  • 227 + 8667497 = 8667724
  • 293 + 8667431 = 8667724

Showing the first eight; more decompositions exist.
