Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182230, here are decompositions:

29 + 182201 = 182230
53 + 182177 = 182230
71 + 182159 = 182230
89 + 182141 = 182230
101 + 182129 = 182230
107 + 182123 = 182230
131 + 182099 = 182230
173 + 182057 = 182230

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 182,230 and was likely granted around 1875.

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