Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7320, here are decompositions:
- 11 + 7309 = 7320
- 13 + 7307 = 7320
- 23 + 7297 = 7320
- 37 + 7283 = 7320
- 67 + 7253 = 7320
- 73 + 7247 = 7320
- 83 + 7237 = 7320
- 101 + 7219 = 7320
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 7320 first appears in π at position 10,412 of the decimal expansion (the 10,412ordinal-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.
