Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80800, here are decompositions:
- 11 + 80789 = 80800
- 17 + 80783 = 80800
- 23 + 80777 = 80800
- 53 + 80747 = 80800
- 113 + 80687 = 80800
- 131 + 80669 = 80800
- 149 + 80651 = 80800
- 173 + 80627 = 80800
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 80800 first appears in π at position 26,035 of the decimal expansion (the 26,035ordinal-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.
