Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105920, here are decompositions:

7 + 105913 = 105920
13 + 105907 = 105920
37 + 105883 = 105920
103 + 105817 = 105920
151 + 105769 = 105920
193 + 105727 = 105920
229 + 105691 = 105920
271 + 105649 = 105920

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 105.920 and was likely granted around 1870.

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