Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17420, here are decompositions:
- 3 + 17417 = 17420
- 19 + 17401 = 17420
- 31 + 17389 = 17420
- 37 + 17383 = 17420
- 43 + 17377 = 17420
- 61 + 17359 = 17420
- 79 + 17341 = 17420
- 103 + 17317 = 17420
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 17420 first appears in π at position 89,537 of the decimal expansion (the 89,537ordinal-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.
