Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581604, here are decompositions:
- 5 + 581599 = 581604
- 7 + 581597 = 581604
- 31 + 581573 = 581604
- 47 + 581557 = 581604
- 53 + 581551 = 581604
- 83 + 581521 = 581604
- 113 + 581491 = 581604
- 131 + 581473 = 581604
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 581,604 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
