Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528304, here are decompositions:
- 5 + 528299 = 528304
- 41 + 528263 = 528304
- 107 + 528197 = 528304
- 113 + 528191 = 528304
- 137 + 528167 = 528304
- 167 + 528137 = 528304
- 173 + 528131 = 528304
- 197 + 528107 = 528304
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 528,304 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 528304 first appears in π at position 46,698 of the decimal expansion (the 46,698ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
