Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180968, here are decompositions:

19 + 180949 = 180968
61 + 180907 = 180968
97 + 180871 = 180968
157 + 180811 = 180968
421 + 180547 = 180968
457 + 180511 = 180968
577 + 180391 = 180968
607 + 180361 = 180968

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 180,968 and was likely granted around 1875.

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