Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168724, here are decompositions:

  • 5 + 168719 = 168724
  • 11 + 168713 = 168724
  • 47 + 168677 = 168724
  • 107 + 168617 = 168724
  • 191 + 168533 = 168724
  • 197 + 168527 = 168724
  • 233 + 168491 = 168724
  • 401 + 168323 = 168724

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 168,724 and was likely granted around 1874.

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