Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666622, here are decompositions:

  • 31 + 8666591 = 8666622
  • 79 + 8666543 = 8666622
  • 89 + 8666533 = 8666622
  • 103 + 8666519 = 8666622
  • 109 + 8666513 = 8666622
  • 131 + 8666491 = 8666622
  • 163 + 8666459 = 8666622
  • 179 + 8666443 = 8666622

Showing the first eight; more decompositions exist.
