Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185384, here are decompositions:

13 + 185371 = 185384
61 + 185323 = 185384
151 + 185233 = 185384
163 + 185221 = 185384
223 + 185161 = 185384
307 + 185077 = 185384
313 + 185071 = 185384
541 + 184843 = 185384

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 185,384 and was likely granted around 1875.

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