Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67140, here are decompositions:
- 11 + 67129 = 67140
- 19 + 67121 = 67140
- 37 + 67103 = 67140
- 61 + 67079 = 67140
- 67 + 67073 = 67140
- 79 + 67061 = 67140
- 83 + 67057 = 67140
- 97 + 67043 = 67140
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 67140 first appears in π at position 53,105 of the decimal expansion (the 53,105ordinal-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.
