Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188012, here are decompositions:

61 + 187951 = 188012
103 + 187909 = 188012
151 + 187861 = 188012
313 + 187699 = 188012
373 + 187639 = 188012
379 + 187633 = 188012
439 + 187573 = 188012
499 + 187513 = 188012

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 188,012 and was likely granted around 1875.

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