Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3256, here are decompositions:
- 3 + 3253 = 3256
- 5 + 3251 = 3256
- 47 + 3209 = 3256
- 53 + 3203 = 3256
- 89 + 3167 = 3256
- 137 + 3119 = 3256
- 167 + 3089 = 3256
- 173 + 3083 = 3256
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 3256 first appears in π at position 7,417 of the decimal expansion (the 7,417ordinal-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.
