Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105620, here are decompositions:

7 + 105613 = 105620
13 + 105607 = 105620
19 + 105601 = 105620
79 + 105541 = 105620
103 + 105517 = 105620
223 + 105397 = 105620
241 + 105379 = 105620
283 + 105337 = 105620

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 105,620 and was likely granted around 1870.

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