Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168868, here are decompositions:

  • 5 + 168863 = 168868
  • 17 + 168851 = 168868
  • 107 + 168761 = 168868
  • 131 + 168737 = 168868
  • 137 + 168731 = 168868
  • 149 + 168719 = 168868
  • 191 + 168677 = 168868
  • 239 + 168629 = 168868

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 168,868 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
