Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67742, here are decompositions:
- 19 + 67723 = 67742
- 43 + 67699 = 67742
- 163 + 67579 = 67742
- 211 + 67531 = 67742
- 313 + 67429 = 67742
- 331 + 67411 = 67742
- 373 + 67369 = 67742
- 523 + 67219 = 67742
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 67742 first appears in π at position 42,880 of the decimal expansion (the 42,880ordinal-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.
