Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167680, here are decompositions:

  • 3 + 167677 = 167680
  • 17 + 167663 = 167680
  • 47 + 167633 = 167680
  • 53 + 167627 = 167680
  • 59 + 167621 = 167680
  • 83 + 167597 = 167680
  • 137 + 167543 = 167680
  • 197 + 167483 = 167680

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 167,680 and was likely granted around 1874.

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