Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672690, here are decompositions:

  • 3 + 8672687 = 8672690
  • 31 + 8672659 = 8672690
  • 43 + 8672647 = 8672690
  • 127 + 8672563 = 8672690
  • 139 + 8672551 = 8672690
  • 151 + 8672539 = 8672690
  • 163 + 8672527 = 8672690
  • 181 + 8672509 = 8672690

Showing the first eight; more decompositions exist.
