Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522464, here are decompositions:

5 + 31522459 = 31522464
13 + 31522451 = 31522464
23 + 31522441 = 31522464
31 + 31522433 = 31522464
53 + 31522411 = 31522464
101 + 31522363 = 31522464
107 + 31522357 = 31522464
137 + 31522327 = 31522464

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.254.160.

Address: 1.224.254.160
Class: public
IPv4-mapped IPv6: ::ffff:1.224.254.160

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

Position in π

The digit sequence 31522464 first appears in π at position 565,822 of the decimal expansion (the 565,822ordinal-suffix:nd 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.
