Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185506, here are decompositions:

23 + 185483 = 185506
29 + 185477 = 185506
137 + 185369 = 185506
179 + 185327 = 185506
197 + 185309 = 185506
239 + 185267 = 185506
263 + 185243 = 185506
317 + 185189 = 185506

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 185,506 and was likely granted around 1875.

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