Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621706, here are decompositions:

  • 13 + 8621693 = 8621706
  • 29 + 8621677 = 8621706
  • 53 + 8621653 = 8621706
  • 83 + 8621623 = 8621706
  • 89 + 8621617 = 8621706
  • 97 + 8621609 = 8621706
  • 227 + 8621479 = 8621706
  • 229 + 8621477 = 8621706

Showing the first eight; more decompositions exist.
