Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105768, here are decompositions:

  • 7 + 105761 = 105768
  • 17 + 105751 = 105768
  • 41 + 105727 = 105768
  • 67 + 105701 = 105768
  • 101 + 105667 = 105768
  • 149 + 105619 = 105768
  • 167 + 105601 = 105768
  • 211 + 105557 = 105768

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 105,768 and was likely granted around 1870.

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