Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4572, here are decompositions:
- 5 + 4567 = 4572
- 11 + 4561 = 4572
- 23 + 4549 = 4572
- 53 + 4519 = 4572
- 59 + 4513 = 4572
- 79 + 4493 = 4572
- 89 + 4483 = 4572
- 109 + 4463 = 4572
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 4572 first appears in π at position 12,268 of the decimal expansion (the 12,268ordinal-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.
