Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181246, here are decompositions:

3 + 181243 = 181246
47 + 181199 = 181246
53 + 181193 = 181246
89 + 181157 = 181246
227 + 181019 = 181246
449 + 180797 = 181246
467 + 180779 = 181246
599 + 180647 = 181246

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 181,246 and was likely granted around 1875.

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