Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181050, here are decompositions:

11 + 181039 = 181050
19 + 181031 = 181050
31 + 181019 = 181050
47 + 181003 = 181050
101 + 180949 = 181050
167 + 180883 = 181050
179 + 180871 = 181050
239 + 180811 = 181050

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 181,050 and was likely granted around 1875.

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