Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148140, here are decompositions:

17 + 148123 = 148140
61 + 148079 = 148140
67 + 148073 = 148140
79 + 148061 = 148140
127 + 148013 = 148140
163 + 147977 = 148140
191 + 147949 = 148140
277 + 147863 = 148140

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 148,140 and was likely granted around 1873.

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