Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642960, here are decompositions:

  • 13 + 8642947 = 8642960
  • 97 + 8642863 = 8642960
  • 103 + 8642857 = 8642960
  • 199 + 8642761 = 8642960
  • 379 + 8642581 = 8642960
  • 577 + 8642383 = 8642960
  • 631 + 8642329 = 8642960
  • 787 + 8642173 = 8642960

Showing the first eight; more decompositions exist.
