Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516520, here are decompositions:
- 3 + 516517 = 516520
- 71 + 516449 = 516520
- 83 + 516437 = 516520
- 89 + 516431 = 516520
- 113 + 516407 = 516520
- 149 + 516371 = 516520
- 197 + 516323 = 516520
- 227 + 516293 = 516520
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 516,520 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
