Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 571640, here are decompositions:
- 7 + 571633 = 571640
- 37 + 571603 = 571640
- 61 + 571579 = 571640
- 109 + 571531 = 571640
- 163 + 571477 = 571640
- 241 + 571399 = 571640
- 271 + 571369 = 571640
- 337 + 571303 = 571640
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 571,640 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
