Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42372, here are decompositions:
- 13 + 42359 = 42372
- 23 + 42349 = 42372
- 41 + 42331 = 42372
- 73 + 42299 = 42372
- 79 + 42293 = 42372
- 89 + 42283 = 42372
- 149 + 42223 = 42372
- 151 + 42221 = 42372
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 42372 first appears in π at position 15,276 of the decimal expansion (the 15,276ordinal-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.
