Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105180, here are decompositions:

7 + 105173 = 105180
13 + 105167 = 105180
37 + 105143 = 105180
43 + 105137 = 105180
73 + 105107 = 105180
83 + 105097 = 105180
109 + 105071 = 105180
149 + 105031 = 105180

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 105.180 and was likely granted around 1870.

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