Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9742, here are decompositions:
- 3 + 9739 = 9742
- 23 + 9719 = 9742
- 53 + 9689 = 9742
- 113 + 9629 = 9742
- 191 + 9551 = 9742
- 251 + 9491 = 9742
- 263 + 9479 = 9742
- 269 + 9473 = 9742
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 9742 first appears in π at position 9,778 of the decimal expansion (the 9,778ordinal-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.
