Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491010, here are decompositions:
- 7 + 491003 = 491010
- 17 + 490993 = 491010
- 19 + 490991 = 491010
- 41 + 490969 = 491010
- 43 + 490967 = 491010
- 53 + 490957 = 491010
- 59 + 490951 = 491010
- 61 + 490949 = 491010
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 491,010 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
