Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136900, here are decompositions:

3 + 136897 = 136900
11 + 136889 = 136900
17 + 136883 = 136900
41 + 136859 = 136900
59 + 136841 = 136900
89 + 136811 = 136900
131 + 136769 = 136900
149 + 136751 = 136900

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 136,900 and was likely granted around 1872.

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