Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105390, here are decompositions:

11 + 105379 = 105390
17 + 105373 = 105390
23 + 105367 = 105390
29 + 105361 = 105390
31 + 105359 = 105390
53 + 105337 = 105390
59 + 105331 = 105390
67 + 105323 = 105390

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 105 390 and was likely granted around 1870.

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