Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97864, here are decompositions:
- 3 + 97861 = 97864
- 5 + 97859 = 97864
- 17 + 97847 = 97864
- 23 + 97841 = 97864
- 191 + 97673 = 97864
- 251 + 97613 = 97864
- 257 + 97607 = 97864
- 281 + 97583 = 97864
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 97864 first appears in π at position 166,105 of the decimal expansion (the 166,105ordinal-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.
