Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73642, here are decompositions:
- 5 + 73637 = 73642
- 29 + 73613 = 73642
- 53 + 73589 = 73642
- 59 + 73583 = 73642
- 71 + 73571 = 73642
- 89 + 73553 = 73642
- 113 + 73529 = 73642
- 263 + 73379 = 73642
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.31.170.

- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.31.170
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 73642 first appears in π at position 4,848 of the decimal expansion (the 4,848ordinal-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.
