Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188556, here are decompositions:

23 + 188533 = 188556
29 + 188527 = 188556
37 + 188519 = 188556
73 + 188483 = 188556
83 + 188473 = 188556
97 + 188459 = 188556
113 + 188443 = 188556
139 + 188417 = 188556

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 188,556 and was likely granted around 1875.

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