Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78508, here are decompositions:
- 11 + 78497 = 78508
- 29 + 78479 = 78508
- 41 + 78467 = 78508
- 71 + 78437 = 78508
- 107 + 78401 = 78508
- 167 + 78341 = 78508
- 191 + 78317 = 78508
- 197 + 78311 = 78508
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 78508 first appears in π at position 20,870 of the decimal expansion (the 20,870ordinal-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.
