Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672688, here are decompositions:

  • 29 + 8672659 = 8672688
  • 41 + 8672647 = 8672688
  • 47 + 8672641 = 8672688
  • 67 + 8672621 = 8672688
  • 127 + 8672561 = 8672688
  • 137 + 8672551 = 8672688
  • 149 + 8672539 = 8672688
  • 179 + 8672509 = 8672688

Showing the first eight; more decompositions exist.
