Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67904, here are decompositions:
- 3 + 67901 = 67904
- 13 + 67891 = 67904
- 37 + 67867 = 67904
- 61 + 67843 = 67904
- 97 + 67807 = 67904
- 103 + 67801 = 67904
- 127 + 67777 = 67904
- 163 + 67741 = 67904
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.9.64.
- Address
- 0.1.9.64
- Class
- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.9.64
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 67904 first appears in π at position 38,710 of the decimal expansion (the 38,710ordinal-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.
