Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166286, here are decompositions:

  • 13 + 166273 = 166286
  • 67 + 166219 = 166286
  • 79 + 166207 = 166286
  • 97 + 166189 = 166286
  • 103 + 166183 = 166286
  • 139 + 166147 = 166286
  • 223 + 166063 = 166286
  • 409 + 165877 = 166286

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 166,286 and was likely granted around 1874.

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