Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88666, here are decompositions:
- 3 + 88663 = 88666
- 5 + 88661 = 88666
- 23 + 88643 = 88666
- 59 + 88607 = 88666
- 167 + 88499 = 88666
- 173 + 88493 = 88666
- 197 + 88469 = 88666
- 239 + 88427 = 88666
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.90.90.
- Address
- 0.1.90.90

- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.90.90
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 88666 first appears in π at position 110,510 of the decimal expansion (the 110,510ordinal-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.
