Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464632, here are decompositions:

  • 13 + 31464619 = 31464632
  • 61 + 31464571 = 31464632
  • 139 + 31464493 = 31464632
  • 151 + 31464481 = 31464632
  • 181 + 31464451 = 31464632
  • 193 + 31464439 = 31464632
  • 211 + 31464421 = 31464632
  • 223 + 31464409 = 31464632

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.28.184.

Address
1.224.28.184
Class
public
IPv4-mapped IPv6
::ffff:1.224.28.184

Public, routable address (assignable to a host on the internet).

Position in π

The digit sequence 31464632 first appears in π at position 841,114 of the decimal expansion (the 841,114ordinal-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.
