Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188300, here are decompositions:

19 + 188281 = 188300
103 + 188197 = 188300
157 + 188143 = 188300
163 + 188137 = 188300
193 + 188107 = 188300
271 + 188029 = 188300
283 + 188017 = 188300
313 + 187987 = 188300

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 188,300 and was likely granted around 1875.

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