Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636178, here are decompositions:

  • 11 + 8636167 = 8636178
  • 37 + 8636141 = 8636178
  • 41 + 8636137 = 8636178
  • 71 + 8636107 = 8636178
  • 97 + 8636081 = 8636178
  • 139 + 8636039 = 8636178
  • 157 + 8636021 = 8636178
  • 179 + 8635999 = 8636178

Showing the first eight; more decompositions exist.
