Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133748, here are decompositions:
- 31 + 133717 = 133748
- 37 + 133711 = 133748
- 79 + 133669 = 133748
- 151 + 133597 = 133748
- 229 + 133519 = 133748
- 331 + 133417 = 133748
- 397 + 133351 = 133748
- 421 + 133327 = 133748
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 133,748 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
