Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528624, here are decompositions:
- 13 + 528611 = 528624
- 97 + 528527 = 528624
- 113 + 528511 = 528624
- 137 + 528487 = 528624
- 191 + 528433 = 528624
- 211 + 528413 = 528624
- 223 + 528401 = 528624
- 233 + 528391 = 528624
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 528,624 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 528624 first appears in π at position 6,827 of the decimal expansion (the 6,827ordinal-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.
