Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131166, here are decompositions:
- 17 + 131149 = 131166
- 23 + 131143 = 131166
- 37 + 131129 = 131166
- 53 + 131113 = 131166
- 103 + 131063 = 131166
- 107 + 131059 = 131166
- 157 + 131009 = 131166
- 179 + 130987 = 131166
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 131,166 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
