Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10100, here are decompositions:
- 7 + 10093 = 10100
- 31 + 10069 = 10100
- 61 + 10039 = 10100
- 127 + 9973 = 10100
- 151 + 9949 = 10100
- 193 + 9907 = 10100
- 199 + 9901 = 10100
- 229 + 9871 = 10100
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 10100 first appears in π at position 852 of the decimal expansion (the 852ordinal-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.
