Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133250, here are decompositions:
- 37 + 133213 = 133250
- 67 + 133183 = 133250
- 97 + 133153 = 133250
- 163 + 133087 = 133250
- 181 + 133069 = 133250
- 199 + 133051 = 133250
- 211 + 133039 = 133250
- 283 + 132967 = 133250
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 133,250 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
