Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181134, here are decompositions:

11 + 181123 = 181134
47 + 181087 = 181134
53 + 181081 = 181134
71 + 181063 = 181134
73 + 181061 = 181134
103 + 181031 = 181134
131 + 181003 = 181134
227 + 180907 = 181134

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 181,134 and was likely granted around 1875.

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