Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621814, here are decompositions:

  • 17 + 8621797 = 8621814
  • 41 + 8621773 = 8621814
  • 67 + 8621747 = 8621814
  • 107 + 8621707 = 8621814
  • 137 + 8621677 = 8621814
  • 191 + 8621623 = 8621814
  • 197 + 8621617 = 8621814
  • 233 + 8621581 = 8621814

Showing the first eight; more decompositions exist.
