Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523420, here are decompositions:
- 3 + 523417 = 523420
- 17 + 523403 = 523420
- 71 + 523349 = 523420
- 113 + 523307 = 523420
- 251 + 523169 = 523420
- 311 + 523109 = 523420
- 389 + 523031 = 523420
- 431 + 522989 = 523420
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 523,420 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
