Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7508, here are decompositions:
- 19 + 7489 = 7508
- 31 + 7477 = 7508
- 97 + 7411 = 7508
- 139 + 7369 = 7508
- 157 + 7351 = 7508
- 199 + 7309 = 7508
- 211 + 7297 = 7508
- 271 + 7237 = 7508
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 7508 first appears in π at position 17,707 of the decimal expansion (the 17,707ordinal-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.
