Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166146, here are decompositions:

  • 47 + 166099 = 166146
  • 83 + 166063 = 166146
  • 103 + 166043 = 166146
  • 163 + 165983 = 166146
  • 199 + 165947 = 166146
  • 263 + 165883 = 166146
  • 269 + 165877 = 166146
  • 313 + 165833 = 166146

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 166,146 and was likely granted around 1874.

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