Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105406, here are decompositions:

  • 5 + 105401 = 105406
  • 17 + 105389 = 105406
  • 47 + 105359 = 105406
  • 83 + 105323 = 105406
  • 137 + 105269 = 105406
  • 167 + 105239 = 105406
  • 179 + 105227 = 105406
  • 233 + 105173 = 105406

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 105 406 and was likely granted around 1870.

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