Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140406, here are decompositions:

5 + 140401 = 140406
43 + 140363 = 140406
67 + 140339 = 140406
73 + 140333 = 140406
89 + 140317 = 140406
109 + 140297 = 140406
137 + 140269 = 140406
157 + 140249 = 140406

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 140,406 and was likely granted around 1872.

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