Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78304, here are decompositions:
- 3 + 78301 = 78304
- 71 + 78233 = 78304
- 101 + 78203 = 78304
- 113 + 78191 = 78304
- 131 + 78173 = 78304
- 137 + 78167 = 78304
- 167 + 78137 = 78304
- 263 + 78041 = 78304
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 78304 first appears in π at position 82,379 of the decimal expansion (the 82,379ordinal-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.
