Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140198, here are decompositions:

7 + 140191 = 140198
31 + 140167 = 140198
127 + 140071 = 140198
199 + 139999 = 140198
211 + 139987 = 140198
229 + 139969 = 140198
277 + 139921 = 140198
307 + 139891 = 140198

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 140,198 and was likely granted around 1872.

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