Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105800, here are decompositions:

  • 31 + 105769 = 105800
  • 67 + 105733 = 105800
  • 73 + 105727 = 105800
  • 109 + 105691 = 105800
  • 127 + 105673 = 105800
  • 151 + 105649 = 105800
  • 181 + 105619 = 105800
  • 193 + 105607 = 105800

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 105.800 and was likely granted around 1870.

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