Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133664, here are decompositions:
- 7 + 133657 = 133664
- 31 + 133633 = 133664
- 67 + 133597 = 133664
- 277 + 133387 = 133664
- 313 + 133351 = 133664
- 337 + 133327 = 133664
- 463 + 133201 = 133664
- 547 + 133117 = 133664
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 133,664 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
