Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468464, here are decompositions:

11 + 31468453 = 31468464
17 + 31468447 = 31468464
61 + 31468403 = 31468464
67 + 31468397 = 31468464
73 + 31468391 = 31468464
127 + 31468337 = 31468464
193 + 31468271 = 31468464
233 + 31468231 = 31468464

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.43.176.

Address: 1.224.43.176
Class: public
IPv4-mapped IPv6: ::ffff:1.224.43.176

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

Position in π

The digit sequence 31468464 first appears in π at position 306,827 of the decimal expansion (the 306,827ordinal-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.
