Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604, here are decompositions:
- 5 + 8599 = 8604
- 7 + 8597 = 8604
- 23 + 8581 = 8604
- 31 + 8573 = 8604
- 41 + 8563 = 8604
- 61 + 8543 = 8604
- 67 + 8537 = 8604
- 83 + 8521 = 8604
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 8604 first appears in π at position 8,864 of the decimal expansion (the 8,864ordinal-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.
