Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183258, here are decompositions:

11 + 183247 = 183258
67 + 183191 = 183258
107 + 183151 = 183258
139 + 183119 = 183258
167 + 183091 = 183258
191 + 183067 = 183258
199 + 183059 = 183258
211 + 183047 = 183258

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 183,258 and was likely granted around 1875.

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