Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1452, here are decompositions:
- 5 + 1447 = 1452
- 13 + 1439 = 1452
- 19 + 1433 = 1452
- 23 + 1429 = 1452
- 29 + 1423 = 1452
- 43 + 1409 = 1452
- 53 + 1399 = 1452
- 71 + 1381 = 1452
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 1452 first appears in π at position 610 of the decimal expansion (the 610ordinal-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.
