Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6842, here are decompositions:
- 13 + 6829 = 6842
- 19 + 6823 = 6842
- 61 + 6781 = 6842
- 79 + 6763 = 6842
- 109 + 6733 = 6842
- 139 + 6703 = 6842
- 151 + 6691 = 6842
- 163 + 6679 = 6842
Showing the first eight; more decompositions exist.

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 6842 first appears in π at position 1,288 of the decimal expansion (the 1,288ordinal-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.
