Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668810, here are decompositions:

  • 11 + 8668799 = 8668810
  • 47 + 8668763 = 8668810
  • 71 + 8668739 = 8668810
  • 89 + 8668721 = 8668810
  • 113 + 8668697 = 8668810
  • 167 + 8668643 = 8668810
  • 173 + 8668637 = 8668810
  • 197 + 8668613 = 8668810

Showing the first eight; more decompositions exist.
