Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64664, here are decompositions:
- 3 + 64661 = 64664
- 31 + 64633 = 64664
- 37 + 64627 = 64664
- 43 + 64621 = 64664
- 73 + 64591 = 64664
- 97 + 64567 = 64664
- 151 + 64513 = 64664
- 181 + 64483 = 64664
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 64664 first appears in π at position 108,457 of the decimal expansion (the 108,457ordinal-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.
