Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43478, here are decompositions:
- 37 + 43441 = 43478
- 67 + 43411 = 43478
- 79 + 43399 = 43478
- 157 + 43321 = 43478
- 241 + 43237 = 43478
- 271 + 43207 = 43478
- 277 + 43201 = 43478
- 499 + 42979 = 43478
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 43478 first appears in π at position 38,188 of the decimal expansion (the 38,188ordinal-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.
