Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608012, here are decompositions:

41 + 31607971 = 31608012
43 + 31607969 = 31608012
103 + 31607909 = 31608012
109 + 31607903 = 31608012
173 + 31607839 = 31608012
181 + 31607831 = 31608012
223 + 31607789 = 31608012
229 + 31607783 = 31608012

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.76.204.

Address: 1.226.76.204
Class: public
IPv4-mapped IPv6: ::ffff:1.226.76.204

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

Position in π

The digit sequence 31608012 first appears in π at position 255,177 of the decimal expansion (the 255,177ordinal-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.
