Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640068, here are decompositions:

  • 67 + 8640001 = 8640068
  • 271 + 8639797 = 8640068
  • 421 + 8639647 = 8640068
  • 607 + 8639461 = 8640068
  • 769 + 8639299 = 8640068
  • 907 + 8639161 = 8640068
  • 919 + 8639149 = 8640068
  • 937 + 8639131 = 8640068

Showing the first eight; more decompositions exist.
