Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17242, here are decompositions:
- 3 + 17239 = 17242
- 11 + 17231 = 17242
- 53 + 17189 = 17242
- 59 + 17183 = 17242
- 83 + 17159 = 17242
- 149 + 17093 = 17242
- 263 + 16979 = 17242
- 311 + 16931 = 17242
Showing the first eight; more decompositions exist.

- ::ffff:0.0.67.90
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 17242 first appears in π at position 251,122 of the decimal expansion (the 251,122ordinal-suffix:nd 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.
