Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131464, here are decompositions:
- 17 + 131447 = 131464
- 23 + 131441 = 131464
- 83 + 131381 = 131464
- 101 + 131363 = 131464
- 107 + 131357 = 131464
- 167 + 131297 = 131464
- 197 + 131267 = 131464
- 233 + 131231 = 131464
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 131,464 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
