Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105140, here are decompositions:

3 + 105137 = 105140
43 + 105097 = 105140
103 + 105037 = 105140
109 + 105031 = 105140
181 + 104959 = 105140
193 + 104947 = 105140
223 + 104917 = 105140
229 + 104911 = 105140

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 105.140 and was likely granted around 1870.

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