Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166670, here are decompositions:

  • 3 + 166667 = 166670
  • 13 + 166657 = 166670
  • 43 + 166627 = 166670
  • 61 + 166609 = 166670
  • 67 + 166603 = 166670
  • 73 + 166597 = 166670
  • 103 + 166567 = 166670
  • 109 + 166561 = 166670

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 166,670 and was likely granted around 1874.

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