Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87654, here are decompositions:
- 5 + 87649 = 87654
- 11 + 87643 = 87654
- 13 + 87641 = 87654
- 23 + 87631 = 87654
- 31 + 87623 = 87654
- 41 + 87613 = 87654
- 67 + 87587 = 87654
- 71 + 87583 = 87654
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.86.102.
- Address
- 0.1.86.102

- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.86.102
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 87654 first appears in π at position 224,001 of the decimal expansion (the 224,001ordinal-suffix:st 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.
