Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516564, here are decompositions:
- 23 + 516541 = 516564
- 43 + 516521 = 516564
- 47 + 516517 = 516564
- 71 + 516493 = 516564
- 107 + 516457 = 516564
- 127 + 516437 = 516564
- 131 + 516433 = 516564
- 157 + 516407 = 516564
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 516,564 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
