Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87162, here are decompositions:
- 11 + 87151 = 87162
- 13 + 87149 = 87162
- 29 + 87133 = 87162
- 41 + 87121 = 87162
- 43 + 87119 = 87162
- 59 + 87103 = 87162
- 79 + 87083 = 87162
- 113 + 87049 = 87162
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.84.122.

- IPv4-mapped IPv6
- ::ffff:0.1.84.122
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 87162 first appears in π at position 202,606 of the decimal expansion (the 202,606ordinal-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.
