Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181452, here are decompositions:

13 + 181439 = 181452
31 + 181421 = 181452
43 + 181409 = 181452
53 + 181399 = 181452
149 + 181303 = 181452
151 + 181301 = 181452
179 + 181273 = 181452
199 + 181253 = 181452

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 181,452 and was likely granted around 1875.

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