Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99998, here are decompositions:
- 7 + 99991 = 99998
- 37 + 99961 = 99998
- 97 + 99901 = 99998
- 127 + 99871 = 99998
- 139 + 99859 = 99998
- 181 + 99817 = 99998
- 211 + 99787 = 99998
- 277 + 99721 = 99998
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 99998 first appears in π at position 764 of the decimal expansion (the 764ordinal-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.
