Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166814, here are decompositions:

  • 7 + 166807 = 166814
  • 31 + 166783 = 166814
  • 73 + 166741 = 166814
  • 157 + 166657 = 166814
  • 211 + 166603 = 166814
  • 397 + 166417 = 166814
  • 421 + 166393 = 166814
  • 457 + 166357 = 166814

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 166,814 and was likely granted around 1874.

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