Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 34720, here are decompositions:
- 17 + 34703 = 34720
- 41 + 34679 = 34720
- 47 + 34673 = 34720
- 53 + 34667 = 34720
- 71 + 34649 = 34720
- 89 + 34631 = 34720
- 107 + 34613 = 34720
- 113 + 34607 = 34720
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 34720 first appears in π at position 175,277 of the decimal expansion (the 175,277ordinal-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.
