Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10142, here are decompositions:
- 3 + 10139 = 10142
- 31 + 10111 = 10142
- 43 + 10099 = 10142
- 73 + 10069 = 10142
- 103 + 10039 = 10142
- 193 + 9949 = 10142
- 211 + 9931 = 10142
- 241 + 9901 = 10142
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 10142 first appears in π at position 25,744 of the decimal expansion (the 25,744ordinal-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.
