Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491604, here are decompositions:
- 11 + 491593 = 491604
- 13 + 491591 = 491604
- 23 + 491581 = 491604
- 67 + 491537 = 491604
- 73 + 491531 = 491604
- 101 + 491503 = 491604
- 103 + 491501 = 491604
- 107 + 491497 = 491604
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 491,604 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
