Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668938, here are decompositions:

  • 37 + 8668901 = 8668938
  • 41 + 8668897 = 8668938
  • 101 + 8668837 = 8668938
  • 107 + 8668831 = 8668938
  • 137 + 8668801 = 8668938
  • 139 + 8668799 = 8668938
  • 197 + 8668741 = 8668938
  • 199 + 8668739 = 8668938

Showing the first eight; more decompositions exist.
