Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666730, here are decompositions:

  • 19 + 8666711 = 8666730
  • 47 + 8666683 = 8666730
  • 103 + 8666627 = 8666730
  • 139 + 8666591 = 8666730
  • 197 + 8666533 = 8666730
  • 211 + 8666519 = 8666730
  • 229 + 8666501 = 8666730
  • 239 + 8666491 = 8666730

Showing the first eight; more decompositions exist.
