Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16722, here are decompositions:
- 19 + 16703 = 16722
- 23 + 16699 = 16722
- 29 + 16693 = 16722
- 31 + 16691 = 16722
- 61 + 16661 = 16722
- 71 + 16651 = 16722
- 73 + 16649 = 16722
- 89 + 16633 = 16722
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 16722 first appears in π at position 3,399 of the decimal expansion (the 3,399ordinal-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.
