Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521304, here are decompositions:
- 5 + 521299 = 521304
- 23 + 521281 = 521304
- 37 + 521267 = 521304
- 53 + 521251 = 521304
- 61 + 521243 = 521304
- 73 + 521231 = 521304
- 103 + 521201 = 521304
- 127 + 521177 = 521304
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 521,304 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
