Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30672, here are decompositions:
- 11 + 30661 = 30672
- 23 + 30649 = 30672
- 29 + 30643 = 30672
- 41 + 30631 = 30672
- 79 + 30593 = 30672
- 113 + 30559 = 30672
- 163 + 30509 = 30672
- 179 + 30493 = 30672
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 30672 first appears in π at position 230,202 of the decimal expansion (the 230,202ordinal-suffix:nd 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.
