Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105844, here are decompositions:

  • 83 + 105761 = 105844
  • 191 + 105653 = 105844
  • 281 + 105563 = 105844
  • 311 + 105533 = 105844
  • 317 + 105527 = 105844
  • 353 + 105491 = 105844
  • 443 + 105401 = 105844
  • 503 + 105341 = 105844

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 105,844 and was likely granted around 1870.

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