Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153140, here are decompositions:

3 + 153137 = 153140
7 + 153133 = 153140
67 + 153073 = 153140
73 + 153067 = 153140
139 + 153001 = 153140
151 + 152989 = 153140
181 + 152959 = 153140
193 + 152947 = 153140

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 153,140 and was likely granted around 1873.

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