Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71204, here are decompositions:
- 13 + 71191 = 71204
- 37 + 71167 = 71204
- 43 + 71161 = 71204
- 61 + 71143 = 71204
- 181 + 71023 = 71204
- 193 + 71011 = 71204
- 223 + 70981 = 71204
- 283 + 70921 = 71204
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 71204 first appears in π at position 39,573 of the decimal expansion (the 39,573ordinal-suffix:rd 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.
