Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133646, here are decompositions:
- 13 + 133633 = 133646
- 103 + 133543 = 133646
- 127 + 133519 = 133646
- 199 + 133447 = 133646
- 229 + 133417 = 133646
- 367 + 133279 = 133646
- 433 + 133213 = 133646
- 463 + 133183 = 133646
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 133,646 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
