Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105500, here are decompositions:

103 + 105397 = 105500
127 + 105373 = 105500
139 + 105361 = 105500
163 + 105337 = 105500
181 + 105319 = 105500
223 + 105277 = 105500
271 + 105229 = 105500
463 + 105037 = 105500

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 105 500 and was likely granted around 1870.

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