Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71822, here are decompositions:
- 13 + 71809 = 71822
- 61 + 71761 = 71822
- 103 + 71719 = 71822
- 109 + 71713 = 71822
- 151 + 71671 = 71822
- 229 + 71593 = 71822
- 271 + 71551 = 71822
- 349 + 71473 = 71822
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.24.142.
- Address
- 0.1.24.142

- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.24.142
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 71822 first appears in π at position 46,045 of the decimal expansion (the 46,045ordinal-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.
