Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1342, here are decompositions:
- 23 + 1319 = 1342
- 41 + 1301 = 1342
- 53 + 1289 = 1342
- 59 + 1283 = 1342
- 83 + 1259 = 1342
- 113 + 1229 = 1342
- 149 + 1193 = 1342
- 179 + 1163 = 1342
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 1342 first appears in π at position 627 of the decimal expansion (the 627ordinal-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.
