Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42204, here are decompositions:
- 7 + 42197 = 42204
- 11 + 42193 = 42204
- 17 + 42187 = 42204
- 23 + 42181 = 42204
- 47 + 42157 = 42204
- 73 + 42131 = 42204
- 103 + 42101 = 42204
- 131 + 42073 = 42204
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 42204 first appears in π at position 110,988 of the decimal expansion (the 110,988ordinal-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.
