Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83742, here are decompositions:
- 5 + 83737 = 83742
- 23 + 83719 = 83742
- 41 + 83701 = 83742
- 53 + 83689 = 83742
- 79 + 83663 = 83742
- 89 + 83653 = 83742
- 101 + 83641 = 83742
- 103 + 83639 = 83742
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.71.30.
- Address
- 0.1.71.30
- Class
- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.71.30
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 83742 first appears in π at position 8,426 of the decimal expansion (the 8,426ordinal-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.
