Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26864, here are decompositions:
- 3 + 26861 = 26864
- 31 + 26833 = 26864
- 43 + 26821 = 26864
- 127 + 26737 = 26864
- 151 + 26713 = 26864
- 163 + 26701 = 26864
- 181 + 26683 = 26864
- 223 + 26641 = 26864
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 26864 first appears in π at position 136,900 of the decimal expansion (the 136,900ordinal-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.
