Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528804, here are decompositions:
- 5 + 528799 = 528804
- 13 + 528791 = 528804
- 41 + 528763 = 528804
- 97 + 528707 = 528804
- 113 + 528691 = 528804
- 131 + 528673 = 528804
- 137 + 528667 = 528804
- 173 + 528631 = 528804
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 528,804 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 528804 first appears in π at position 934,575 of the decimal expansion (the 934,575ordinal-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.
