Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131426, here are decompositions:
- 13 + 131413 = 131426
- 109 + 131317 = 131426
- 223 + 131203 = 131426
- 277 + 131149 = 131426
- 283 + 131143 = 131426
- 313 + 131113 = 131426
- 367 + 131059 = 131426
- 439 + 130987 = 131426
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 131,426 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
