Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166340, here are decompositions:

  • 37 + 166303 = 166340
  • 43 + 166297 = 166340
  • 67 + 166273 = 166340
  • 103 + 166237 = 166340
  • 151 + 166189 = 166340
  • 157 + 166183 = 166340
  • 193 + 166147 = 166340
  • 241 + 166099 = 166340

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 166,340 and was likely granted around 1874.

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