Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67784, here are decompositions:
- 7 + 67777 = 67784
- 43 + 67741 = 67784
- 61 + 67723 = 67784
- 307 + 67477 = 67784
- 331 + 67453 = 67784
- 337 + 67447 = 67784
- 373 + 67411 = 67784
- 523 + 67261 = 67784
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.8.200.
- Address
- 0.1.8.200
- Class
- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.8.200
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 67784 first appears in π at position 300,510 of the decimal expansion (the 300,510ordinal-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.
