Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538094, here are decompositions:

23 + 31538071 = 31538094
31 + 31538063 = 31538094
41 + 31538053 = 31538094
47 + 31538047 = 31538094
61 + 31538033 = 31538094
97 + 31537997 = 31538094
113 + 31537981 = 31538094
173 + 31537921 = 31538094

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.59.174.

Address: 1.225.59.174
Class: public
IPv4-mapped IPv6: ::ffff:1.225.59.174

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

Position in π

The digit sequence 31538094 first appears in π at position 63,200 of the decimal expansion (the 63,200ordinal-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.
