Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133988, here are decompositions:
- 7 + 133981 = 133988
- 157 + 133831 = 133988
- 271 + 133717 = 133988
- 277 + 133711 = 133988
- 331 + 133657 = 133988
- 541 + 133447 = 133988
- 571 + 133417 = 133988
- 601 + 133387 = 133988
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 133,988 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
