Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42136, here are decompositions:
- 5 + 42131 = 42136
- 47 + 42089 = 42136
- 53 + 42083 = 42136
- 113 + 42023 = 42136
- 137 + 41999 = 42136
- 167 + 41969 = 42136
- 179 + 41957 = 42136
- 233 + 41903 = 42136
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 42136 first appears in π at position 435,073 of the decimal expansion (the 435,073ordinal-suffix:rd 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.
