Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180084, here are decompositions:

7 + 180077 = 180084
11 + 180073 = 180084
13 + 180071 = 180084
31 + 180053 = 180084
41 + 180043 = 180084
61 + 180023 = 180084
83 + 180001 = 180084
103 + 179981 = 180084

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 180,084 and was likely granted around 1875.

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