Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43164, here are decompositions:
- 5 + 43159 = 43164
- 13 + 43151 = 43164
- 31 + 43133 = 43164
- 47 + 43117 = 43164
- 61 + 43103 = 43164
- 71 + 43093 = 43164
- 97 + 43067 = 43164
- 101 + 43063 = 43164
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 43164 first appears in π at position 206,806 of the decimal expansion (the 206,806ordinal-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.
