Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491470, here are decompositions:
- 41 + 491429 = 491470
- 47 + 491423 = 491470
- 53 + 491417 = 491470
- 113 + 491357 = 491470
- 131 + 491339 = 491470
- 137 + 491333 = 491470
- 173 + 491297 = 491470
- 191 + 491279 = 491470
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 491,470 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
