Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23142, here are decompositions:
- 11 + 23131 = 23142
- 43 + 23099 = 23142
- 61 + 23081 = 23142
- 71 + 23071 = 23142
- 79 + 23063 = 23142
- 83 + 23059 = 23142
- 89 + 23053 = 23142
- 101 + 23041 = 23142
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 23142 first appears in π at position 51,530 of the decimal expansion (the 51,530ordinal-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.
