Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649768, here are decompositions:

  • 5 + 8649763 = 8649768
  • 7 + 8649761 = 8649768
  • 11 + 8649757 = 8649768
  • 47 + 8649721 = 8649768
  • 79 + 8649689 = 8649768
  • 97 + 8649671 = 8649768
  • 107 + 8649661 = 8649768
  • 131 + 8649637 = 8649768

Showing the first eight; more decompositions exist.
