Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520904, here are decompositions:
- 37 + 520867 = 520904
- 67 + 520837 = 520904
- 157 + 520747 = 520904
- 271 + 520633 = 520904
- 283 + 520621 = 520904
- 337 + 520567 = 520904
- 457 + 520447 = 520904
- 523 + 520381 = 520904
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 520,904 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
