Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187000, here are decompositions:

41 + 186959 = 187000
53 + 186947 = 187000
83 + 186917 = 187000
131 + 186869 = 187000
227 + 186773 = 187000
239 + 186761 = 187000
257 + 186743 = 187000
293 + 186707 = 187000

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 187,000 and was likely granted around 1875.

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