Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80842, here are decompositions:
- 11 + 80831 = 80842
- 23 + 80819 = 80842
- 53 + 80789 = 80842
- 59 + 80783 = 80842
- 173 + 80669 = 80842
- 191 + 80651 = 80842
- 239 + 80603 = 80842
- 353 + 80489 = 80842
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 80842 first appears in π at position 60,264 of the decimal expansion (the 60,264ordinal-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.
