Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163564, here are decompositions:
- 3 + 163561 = 163564
- 47 + 163517 = 163564
- 83 + 163481 = 163564
- 131 + 163433 = 163564
- 197 + 163367 = 163564
- 227 + 163337 = 163564
- 257 + 163307 = 163564
- 353 + 163211 = 163564
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 163,564 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 163564 first appears in π at position 627,351 of the decimal expansion (the 627,351ordinal-suffix:st 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.
