Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105380, here are decompositions:

7 + 105373 = 105380
13 + 105367 = 105380
19 + 105361 = 105380
43 + 105337 = 105380
61 + 105319 = 105380
103 + 105277 = 105380
127 + 105253 = 105380
151 + 105229 = 105380

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 105.380 and was likely granted around 1870.

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