Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42246, here are decompositions:
- 7 + 42239 = 42246
- 19 + 42227 = 42246
- 23 + 42223 = 42246
- 37 + 42209 = 42246
- 53 + 42193 = 42246
- 59 + 42187 = 42246
- 67 + 42179 = 42246
- 89 + 42157 = 42246
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 42246 first appears in π at position 181,500 of the decimal expansion (the 181,500ordinal-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.
