Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131106, here are decompositions:

5 + 131101 = 131106
43 + 131063 = 131106
47 + 131059 = 131106
83 + 131023 = 131106
97 + 131009 = 131106
137 + 130969 = 131106
149 + 130957 = 131106
179 + 130927 = 131106

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 131,106 and was likely granted around 1872.

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