Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71042, here are decompositions:
- 3 + 71039 = 71042
- 19 + 71023 = 71042
- 31 + 71011 = 71042
- 43 + 70999 = 71042
- 61 + 70981 = 71042
- 73 + 70969 = 71042
- 151 + 70891 = 71042
- 163 + 70879 = 71042
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 71042 first appears in π at position 93,905 of the decimal expansion (the 93,905ordinal-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.
