Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564644, here are decompositions:
- 37 + 564607 = 564644
- 181 + 564463 = 564644
- 271 + 564373 = 564644
- 277 + 564367 = 564644
- 331 + 564313 = 564644
- 337 + 564307 = 564644
- 373 + 564271 = 564644
- 541 + 564103 = 564644
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 564,644 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
