Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180082, here are decompositions:

5 + 180077 = 180082
11 + 180071 = 180082
29 + 180053 = 180082
59 + 180023 = 180082
83 + 179999 = 180082
101 + 179981 = 180082
113 + 179969 = 180082
131 + 179951 = 180082

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 180,082 and was likely granted around 1875.

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