Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565564, here are decompositions:
- 5 + 565559 = 565564
- 11 + 565553 = 565564
- 47 + 565517 = 565564
- 53 + 565511 = 565564
- 101 + 565463 = 565564
- 113 + 565451 = 565564
- 137 + 565427 = 565564
- 173 + 565391 = 565564
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 565,564 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 565564 first appears in π at position 165,016 of the decimal expansion (the 165,016ordinal-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.
