Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80664, here are decompositions:
- 7 + 80657 = 80664
- 13 + 80651 = 80664
- 37 + 80627 = 80664
- 43 + 80621 = 80664
- 53 + 80611 = 80664
- 61 + 80603 = 80664
- 97 + 80567 = 80664
- 107 + 80557 = 80664
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 80664 first appears in π at position 169,528 of the decimal expansion (the 169,528ordinal-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.
