Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4666, here are decompositions:
- 3 + 4663 = 4666
- 17 + 4649 = 4666
- 23 + 4643 = 4666
- 29 + 4637 = 4666
- 83 + 4583 = 4666
- 149 + 4517 = 4666
- 173 + 4493 = 4666
- 257 + 4409 = 4666
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 4666 first appears in π at position 2,439 of the decimal expansion (the 2,439ordinal-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.
