Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133666, here are decompositions:
- 17 + 133649 = 133666
- 83 + 133583 = 133666
- 107 + 133559 = 133666
- 167 + 133499 = 133666
- 173 + 133493 = 133666
- 227 + 133439 = 133666
- 263 + 133403 = 133666
- 317 + 133349 = 133666
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 133,666 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
