Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180682, here are decompositions:

3 + 180679 = 180682
53 + 180629 = 180682
59 + 180623 = 180682
113 + 180569 = 180682
149 + 180533 = 180682
179 + 180503 = 180682
191 + 180491 = 180682
263 + 180419 = 180682

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 180,682 and was likely granted around 1875.

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