Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165604, here are decompositions:
- 3 + 165601 = 165604
- 17 + 165587 = 165604
- 53 + 165551 = 165604
- 71 + 165533 = 165604
- 167 + 165437 = 165604
- 293 + 165311 = 165604
- 311 + 165293 = 165604
- 317 + 165287 = 165604
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 165,604 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
