Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43504, here are decompositions:
- 5 + 43499 = 43504
- 17 + 43487 = 43504
- 23 + 43481 = 43504
- 47 + 43457 = 43504
- 53 + 43451 = 43504
- 101 + 43403 = 43504
- 107 + 43397 = 43504
- 113 + 43391 = 43504
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 43504 first appears in π at position 43,058 of the decimal expansion (the 43,058ordinal-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.
