Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105838, here are decompositions:

  • 71 + 105767 = 105838
  • 137 + 105701 = 105838
  • 281 + 105557 = 105838
  • 311 + 105527 = 105838
  • 347 + 105491 = 105838
  • 389 + 105449 = 105838
  • 401 + 105437 = 105838
  • 431 + 105407 = 105838

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 105,838 and was likely granted around 1870.

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