Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166176, here are decompositions:

  • 7 + 166169 = 166176
  • 19 + 166157 = 166176
  • 29 + 166147 = 166176
  • 113 + 166063 = 166176
  • 149 + 166027 = 166176
  • 163 + 166013 = 166176
  • 193 + 165983 = 166176
  • 229 + 165947 = 166176

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 166,176 and was likely granted around 1874.

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