Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78498, here are decompositions:
- 11 + 78487 = 78498
- 19 + 78479 = 78498
- 31 + 78467 = 78498
- 59 + 78439 = 78498
- 61 + 78437 = 78498
- 71 + 78427 = 78498
- 97 + 78401 = 78498
- 131 + 78367 = 78498
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 78498 first appears in π at position 27,927 of the decimal expansion (the 27,927ordinal-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.
