Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9784, here are decompositions:
- 3 + 9781 = 9784
- 17 + 9767 = 9784
- 41 + 9743 = 9784
- 107 + 9677 = 9784
- 197 + 9587 = 9784
- 233 + 9551 = 9784
- 251 + 9533 = 9784
- 263 + 9521 = 9784
Showing the first eight; more decompositions exist.

Unspecified address (0.0.0.0/8) — "this network" placeholder.
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 9784 first appears in π at position 2,634 of the decimal expansion (the 2,634ordinal-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.
