Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189080, here are decompositions:

13 + 189067 = 189080
19 + 189061 = 189080
37 + 189043 = 189080
61 + 189019 = 189080
97 + 188983 = 189080
127 + 188953 = 189080
139 + 188941 = 189080
211 + 188869 = 189080

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 189,080 and was likely granted around 1875.

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