Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105660, here are decompositions:

7 + 105653 = 105660
11 + 105649 = 105660
41 + 105619 = 105660
47 + 105613 = 105660
53 + 105607 = 105660
59 + 105601 = 105660
97 + 105563 = 105660
103 + 105557 = 105660

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 105.660 and was likely granted around 1870.

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