Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140144, here are decompositions:

73 + 140071 = 140144
157 + 139987 = 140144
163 + 139981 = 140144
223 + 139921 = 140144
283 + 139861 = 140144
307 + 139837 = 140144
313 + 139831 = 140144
331 + 139813 = 140144

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 140,144 and was likely granted around 1872.

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