Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105154, here are decompositions:

11 + 105143 = 105154
17 + 105137 = 105154
47 + 105107 = 105154
83 + 105071 = 105154
131 + 105023 = 105154
167 + 104987 = 105154
263 + 104891 = 105154
353 + 104801 = 105154

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 105,154 and was likely granted around 1870.

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