Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64004, here are decompositions:
- 7 + 63997 = 64004
- 97 + 63907 = 64004
- 103 + 63901 = 64004
- 151 + 63853 = 64004
- 163 + 63841 = 64004
- 181 + 63823 = 64004
- 211 + 63793 = 64004
- 223 + 63781 = 64004
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 64004 first appears in π at position 5,091 of the decimal expansion (the 5,091ordinal-suffix:st 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.
