Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188912, here are decompositions:

43 + 188869 = 188912
79 + 188833 = 188912
193 + 188719 = 188912
211 + 188701 = 188912
349 + 188563 = 188912
379 + 188533 = 188912
421 + 188491 = 188912
439 + 188473 = 188912

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 188,912 and was likely granted around 1875.

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