Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166358, here are decompositions:

  • 7 + 166351 = 166358
  • 61 + 166297 = 166358
  • 139 + 166219 = 166358
  • 151 + 166207 = 166358
  • 211 + 166147 = 166358
  • 277 + 166081 = 166358
  • 331 + 166027 = 166358
  • 337 + 166021 = 166358

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 166,358 and was likely granted around 1874.

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