Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6402, here are decompositions:
- 5 + 6397 = 6402
- 13 + 6389 = 6402
- 23 + 6379 = 6402
- 29 + 6373 = 6402
- 41 + 6361 = 6402
- 43 + 6359 = 6402
- 59 + 6343 = 6402
- 73 + 6329 = 6402
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 6402 first appears in π at position 1,366 of the decimal expansion (the 1,366ordinal-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.
