Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491330, here are decompositions:
- 3 + 491327 = 491330
- 31 + 491299 = 491330
- 79 + 491251 = 491330
- 163 + 491167 = 491330
- 181 + 491149 = 491330
- 193 + 491137 = 491330
- 271 + 491059 = 491330
- 337 + 490993 = 491330
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 491,330 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
