Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133340, here are decompositions:
- 3 + 133337 = 133340
- 13 + 133327 = 133340
- 19 + 133321 = 133340
- 37 + 133303 = 133340
- 61 + 133279 = 133340
- 79 + 133261 = 133340
- 127 + 133213 = 133340
- 139 + 133201 = 133340
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 133,340 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
