Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61722, here are decompositions:
- 5 + 61717 = 61722
- 19 + 61703 = 61722
- 41 + 61681 = 61722
- 71 + 61651 = 61722
- 79 + 61643 = 61722
- 109 + 61613 = 61722
- 113 + 61609 = 61722
- 139 + 61583 = 61722
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.0.241.26.
- Address
- 0.0.241.26

- reserved
- IPv4-mapped IPv6
- ::ffff:0.0.241.26
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 61722 first appears in π at position 183,713 of the decimal expansion (the 183,713ordinal-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.
