Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180012, here are decompositions:

5 + 180007 = 180012
11 + 180001 = 180012
13 + 179999 = 180012
23 + 179989 = 180012
31 + 179981 = 180012
43 + 179969 = 180012
59 + 179953 = 180012
61 + 179951 = 180012

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 180,012 and was likely granted around 1875.

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