Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40112, here are decompositions:
- 13 + 40099 = 40112
- 19 + 40093 = 40112
- 73 + 40039 = 40112
- 103 + 40009 = 40112
- 211 + 39901 = 40112
- 229 + 39883 = 40112
- 271 + 39841 = 40112
- 283 + 39829 = 40112
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 40112 first appears in π at position 58,723 of the decimal expansion (the 58,723ordinal-suffix:rd 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.
