Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166316, here are decompositions:

  • 13 + 166303 = 166316
  • 19 + 166297 = 166316
  • 43 + 166273 = 166316
  • 79 + 166237 = 166316
  • 97 + 166219 = 166316
  • 109 + 166207 = 166316
  • 127 + 166189 = 166316
  • 433 + 165883 = 166316

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 166,316 and was likely granted around 1874.

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