Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180008, here are decompositions:

7 + 180001 = 180008
19 + 179989 = 180008
61 + 179947 = 180008
109 + 179899 = 180008
181 + 179827 = 180008
229 + 179779 = 180008
271 + 179737 = 180008
337 + 179671 = 180008

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 180,008 and was likely granted around 1875.

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