Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564520, here are decompositions:
- 23 + 564497 = 564520
- 29 + 564491 = 564520
- 53 + 564467 = 564520
- 71 + 564449 = 564520
- 83 + 564437 = 564520
- 101 + 564419 = 564520
- 113 + 564407 = 564520
- 149 + 564371 = 564520
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 564,520 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 564520 first appears in π at position 870,103 of the decimal expansion (the 870,103ordinal-suffix:rd 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.
