Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105854, here are decompositions:

  • 37 + 105817 = 105854
  • 103 + 105751 = 105854
  • 127 + 105727 = 105854
  • 163 + 105691 = 105854
  • 181 + 105673 = 105854
  • 241 + 105613 = 105854
  • 313 + 105541 = 105854
  • 337 + 105517 = 105854

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 105 854 and was likely granted around 1870.

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