Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9904, here are decompositions:
- 3 + 9901 = 9904
- 17 + 9887 = 9904
- 47 + 9857 = 9904
- 53 + 9851 = 9904
- 71 + 9833 = 9904
- 101 + 9803 = 9904
- 113 + 9791 = 9904
- 137 + 9767 = 9904
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 9904 first appears in π at position 4,549 of the decimal expansion (the 4,549ordinal-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.
