Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43672, here are decompositions:
- 3 + 43669 = 43672
- 11 + 43661 = 43672
- 23 + 43649 = 43672
- 59 + 43613 = 43672
- 131 + 43541 = 43672
- 173 + 43499 = 43672
- 191 + 43481 = 43672
- 269 + 43403 = 43672
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 43672 first appears in π at position 276,099 of the decimal expansion (the 276,099ordinal-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.
