Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140072, here are decompositions:

3 + 140069 = 140072
19 + 140053 = 140072
73 + 139999 = 140072
103 + 139969 = 140072
151 + 139921 = 140072
181 + 139891 = 140072
211 + 139861 = 140072
241 + 139831 = 140072

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 140,072 and was likely granted around 1872.

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