Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182500, here are decompositions:

11 + 182489 = 182500
29 + 182471 = 182500
47 + 182453 = 182500
83 + 182417 = 182500
113 + 182387 = 182500
167 + 182333 = 182500
191 + 182309 = 182500
239 + 182261 = 182500

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 182,500 and was likely granted around 1875.

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