Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163386, here are decompositions:

  • 19 + 163367 = 163386
  • 23 + 163363 = 163386
  • 59 + 163327 = 163386
  • 79 + 163307 = 163386
  • 127 + 163259 = 163386
  • 137 + 163249 = 163386
  • 163 + 163223 = 163386
  • 193 + 163193 = 163386

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 163,386 and was likely granted around 1874.

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