Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565664, here are decompositions:
- 3 + 565661 = 565664
- 13 + 565651 = 565664
- 61 + 565603 = 565664
- 67 + 565597 = 565664
- 97 + 565567 = 565664
- 157 + 565507 = 565664
- 181 + 565483 = 565664
- 223 + 565441 = 565664
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 565,664 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 565664 first appears in π at position 38,677 of the decimal expansion (the 38,677ordinal-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.
