Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140178, here are decompositions:

7 + 140171 = 140178
11 + 140167 = 140178
19 + 140159 = 140178
67 + 140111 = 140178
107 + 140071 = 140178
109 + 140069 = 140178
179 + 139999 = 140178
191 + 139987 = 140178

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 140,178 and was likely granted around 1872.

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