Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41564, here are decompositions:
- 43 + 41521 = 41564
- 73 + 41491 = 41564
- 97 + 41467 = 41564
- 151 + 41413 = 41564
- 223 + 41341 = 41564
- 283 + 41281 = 41564
- 307 + 41257 = 41564
- 331 + 41233 = 41564
Showing the first eight; more decompositions exist.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
The digit sequence 41564 first appears in π at position 21,367 of the decimal expansion (the 21,367ordinal-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.
