Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71246, here are decompositions:
- 13 + 71233 = 71246
- 37 + 71209 = 71246
- 79 + 71167 = 71246
- 103 + 71143 = 71246
- 127 + 71119 = 71246
- 157 + 71089 = 71246
- 223 + 71023 = 71246
- 277 + 70969 = 71246
Showing the first eight; more decompositions exist.
As an unsigned 32-bit integer, this is the IPv4 address 0.1.22.78.
- Address
- 0.1.22.78
- Class
- reserved
- IPv4-mapped IPv6
- ::ffff:0.1.22.78
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 71246 first appears in π at position 37,847 of the decimal expansion (the 37,847ordinal-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.
