Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131140, here are decompositions:

11 + 131129 = 131140
29 + 131111 = 131140
131 + 131009 = 131140
167 + 130973 = 131140
281 + 130859 = 131140
311 + 130829 = 131140
353 + 130787 = 131140
491 + 130649 = 131140

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 131,140 and was likely granted around 1872.

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