Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643080, here are decompositions:

  • 3 + 8643077 = 8643080
  • 67 + 8643013 = 8643080
  • 223 + 8642857 = 8643080
  • 241 + 8642839 = 8643080
  • 307 + 8642773 = 8643080
  • 499 + 8642581 = 8643080
  • 547 + 8642533 = 8643080
  • 571 + 8642509 = 8643080

Showing the first eight; more decompositions exist.
