Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133816, here are decompositions:
- 3 + 133813 = 133816
- 5 + 133811 = 133816
- 47 + 133769 = 133816
- 83 + 133733 = 133816
- 107 + 133709 = 133816
- 167 + 133649 = 133816
- 233 + 133583 = 133816
- 257 + 133559 = 133816
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 133,816 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
