Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133238, here are decompositions:
- 37 + 133201 = 133238
- 151 + 133087 = 133238
- 199 + 133039 = 133238
- 271 + 132967 = 133238
- 277 + 132961 = 133238
- 379 + 132859 = 133238
- 421 + 132817 = 133238
- 487 + 132751 = 133238
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 133,238 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
