Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514792, here are decompositions:

  • 3 + 31514789 = 31514792
  • 61 + 31514731 = 31514792
  • 103 + 31514689 = 31514792
  • 139 + 31514653 = 31514792
  • 151 + 31514641 = 31514792
  • 163 + 31514629 = 31514792
  • 193 + 31514599 = 31514792
  • 241 + 31514551 = 31514792

Showing the first eight; more decompositions exist.

As an unsigned 32-bit integer, this is the IPv4 address 1.224.224.168.

Address
1.224.224.168
Class
public
IPv4-mapped IPv6
::ffff:1.224.224.168

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

Position in π

The digit sequence 31514792 first appears in π at position 821,717 of the decimal expansion (the 821,717ordinal-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.
