Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725806, here are decompositions:

  • 7 + 8725799 = 8725806
  • 73 + 8725733 = 8725806
  • 107 + 8725699 = 8725806
  • 137 + 8725669 = 8725806
  • 149 + 8725657 = 8725806
  • 163 + 8725643 = 8725806
  • 179 + 8725627 = 8725806
  • 197 + 8725609 = 8725806

Showing the first eight; more decompositions exist.
