Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85504, here are decompositions:
- 17 + 85487 = 85504
- 53 + 85451 = 85504
- 173 + 85331 = 85504
- 191 + 85313 = 85504
- 257 + 85247 = 85504
- 281 + 85223 = 85504
- 311 + 85193 = 85504
- 383 + 85121 = 85504
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.78.0.
- Address
- 0.1.78.0
- Class
- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.78.0
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 85504 first appears in π at position 8,377 of the decimal expansion (the 8,377ordinal-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.
