Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105520, here are decompositions:

3 + 105517 = 105520
11 + 105509 = 105520
17 + 105503 = 105520
29 + 105491 = 105520
53 + 105467 = 105520
71 + 105449 = 105520
83 + 105437 = 105520
113 + 105407 = 105520

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 105.520 and was likely granted around 1870.

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