Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737664, here are decompositions:

  • 7 + 8737657 = 8737664
  • 37 + 8737627 = 8737664
  • 73 + 8737591 = 8737664
  • 163 + 8737501 = 8737664
  • 181 + 8737483 = 8737664
  • 211 + 8737453 = 8737664
  • 241 + 8737423 = 8737664
  • 307 + 8737357 = 8737664

Showing the first eight; more decompositions exist.
