Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180010, here are decompositions:

3 + 180007 = 180010
11 + 179999 = 180010
29 + 179981 = 180010
41 + 179969 = 180010
53 + 179957 = 180010
59 + 179951 = 180010
71 + 179939 = 180010
101 + 179909 = 180010

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 180,010 and was likely granted around 1875.

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