Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2406, here are decompositions:
- 7 + 2399 = 2406
- 13 + 2393 = 2406
- 17 + 2389 = 2406
- 23 + 2383 = 2406
- 29 + 2377 = 2406
- 59 + 2347 = 2406
- 67 + 2339 = 2406
- 73 + 2333 = 2406
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 2406 first appears in π at position 6,014 of the decimal expansion (the 6,014ordinal-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.
