Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131090, here are decompositions:

19 + 131071 = 131090
31 + 131059 = 131090
67 + 131023 = 131090
79 + 131011 = 131090
103 + 130987 = 131090
109 + 130981 = 131090
163 + 130927 = 131090
283 + 130807 = 131090

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 131,090 and was likely granted around 1872.

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