Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4022, here are decompositions:
- 3 + 4019 = 4022
- 19 + 4003 = 4022
- 79 + 3943 = 4022
- 103 + 3919 = 4022
- 199 + 3823 = 4022
- 229 + 3793 = 4022
- 283 + 3739 = 4022
- 313 + 3709 = 4022
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 4022 first appears in π at position 14,137 of the decimal expansion (the 14,137ordinal-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.
