Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474316, here are decompositions:

  • 67 + 31474249 = 31474316
  • 103 + 31474213 = 31474316
  • 283 + 31474033 = 31474316
  • 409 + 31473907 = 31474316
  • 613 + 31473703 = 31474316
  • 733 + 31473583 = 31474316
  • 787 + 31473529 = 31474316
  • 829 + 31473487 = 31474316

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.66.140.

Address
1.224.66.140
Class
public
IPv4-mapped IPv6
::ffff:1.224.66.140

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

Position in π

The digit sequence 31474316 first appears in π at position 245,407 of the decimal expansion (the 245,407ordinal-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.
