Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103556, here are decompositions:

3 + 103553 = 103556
7 + 103549 = 103556
73 + 103483 = 103556
157 + 103399 = 103556
163 + 103393 = 103556
199 + 103357 = 103556
223 + 103333 = 103556
373 + 103183 = 103556

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 103,556 and was likely granted around 1870.

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