Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166412, here are decompositions:

  • 3 + 166409 = 166412
  • 13 + 166399 = 166412
  • 19 + 166393 = 166412
  • 61 + 166351 = 166412
  • 109 + 166303 = 166412
  • 139 + 166273 = 166412
  • 193 + 166219 = 166412
  • 223 + 166189 = 166412

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 166,412 and was likely granted around 1874.

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