Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189140, here are decompositions:

13 + 189127 = 189140
73 + 189067 = 189140
79 + 189061 = 189140
97 + 189043 = 189140
157 + 188983 = 189140
199 + 188941 = 189140
229 + 188911 = 189140
271 + 188869 = 189140

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 189,140 and was likely granted around 1875.

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