Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640852, here are decompositions:

  • 29 + 8640823 = 8640852
  • 53 + 8640799 = 8640852
  • 71 + 8640781 = 8640852
  • 113 + 8640739 = 8640852
  • 139 + 8640713 = 8640852
  • 149 + 8640703 = 8640852
  • 151 + 8640701 = 8640852
  • 163 + 8640689 = 8640852

Showing the first eight; more decompositions exist.
