Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669724, here are decompositions:

  • 23 + 8669701 = 8669724
  • 53 + 8669671 = 8669724
  • 67 + 8669657 = 8669724
  • 73 + 8669651 = 8669724
  • 97 + 8669627 = 8669724
  • 101 + 8669623 = 8669724
  • 103 + 8669621 = 8669724
  • 113 + 8669611 = 8669724

Showing the first eight; more decompositions exist.
