Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1384, here are decompositions:
- 3 + 1381 = 1384
- 11 + 1373 = 1384
- 17 + 1367 = 1384
- 23 + 1361 = 1384
- 83 + 1301 = 1384
- 101 + 1283 = 1384
- 107 + 1277 = 1384
- 167 + 1217 = 1384
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 1384 first appears in π at position 381 of the decimal expansion (the 381ordinal-suffix:st 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.
