Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180004, here are decompositions:

3 + 180001 = 180004
5 + 179999 = 180004
23 + 179981 = 180004
47 + 179957 = 180004
53 + 179951 = 180004
101 + 179903 = 180004
107 + 179897 = 180004
191 + 179813 = 180004

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 180,004 and was likely granted around 1875.

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