Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30342, here are decompositions:
- 19 + 30323 = 30342
- 23 + 30319 = 30342
- 29 + 30313 = 30342
- 71 + 30271 = 30342
- 73 + 30269 = 30342
- 83 + 30259 = 30342
- 89 + 30253 = 30342
- 101 + 30241 = 30342
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 30342 first appears in π at position 133,287 of the decimal expansion (the 133,287ordinal-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.
