Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103868, here are decompositions:

31 + 103837 = 103868
67 + 103801 = 103868
181 + 103687 = 103868
199 + 103669 = 103868
211 + 103657 = 103868
277 + 103591 = 103868
307 + 103561 = 103868
397 + 103471 = 103868

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 103,868 and was likely granted around 1870.

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