Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140148, here are decompositions:

5 + 140143 = 140148
37 + 140111 = 140148
79 + 140069 = 140148
139 + 140009 = 140148
149 + 139999 = 140148
157 + 139991 = 140148
167 + 139981 = 140148
179 + 139969 = 140148

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 140,148 and was likely granted around 1872.

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