Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492062, here are decompositions:

11 + 31492051 = 31492062
29 + 31492033 = 31492062
31 + 31492031 = 31492062
73 + 31491989 = 31492062
79 + 31491983 = 31492062
103 + 31491959 = 31492062
149 + 31491913 = 31492062
181 + 31491881 = 31492062

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.135.222.

Address: 1.224.135.222
Class: public
IPv4-mapped IPv6: ::ffff:1.224.135.222

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

Position in π

The digit sequence 31492062 first appears in π at position 364,555 of the decimal expansion (the 364,555ordinal-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.
