Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622484, here are decompositions:

11 + 31622473 = 31622484
17 + 31622467 = 31622484
107 + 31622377 = 31622484
137 + 31622347 = 31622484
191 + 31622293 = 31622484
197 + 31622287 = 31622484
211 + 31622273 = 31622484
227 + 31622257 = 31622484

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.133.84.

Address: 1.226.133.84
Class: public
IPv4-mapped IPv6: ::ffff:1.226.133.84

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

Position in π

The digit sequence 31622484 first appears in π at position 774,939 of the decimal expansion (the 774,939ordinal-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.
