Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49100, here are decompositions:
- 19 + 49081 = 49100
- 31 + 49069 = 49100
- 43 + 49057 = 49100
- 67 + 49033 = 49100
- 97 + 49003 = 49100
- 109 + 48991 = 49100
- 127 + 48973 = 49100
- 193 + 48907 = 49100
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 49100 first appears in π at position 37,760 of the decimal expansion (the 37,760ordinal-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.
