Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536004, here are decompositions:

23 + 31535981 = 31536004
173 + 31535831 = 31536004
251 + 31535753 = 31536004
257 + 31535747 = 31536004
263 + 31535741 = 31536004
347 + 31535657 = 31536004
587 + 31535417 = 31536004
593 + 31535411 = 31536004

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.51.132.

Address: 1.225.51.132
Class: public
IPv4-mapped IPv6: ::ffff:1.225.51.132

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

Position in π

The digit sequence 31536004 first appears in π at position 664,542 of the decimal expansion (the 664,542ordinal-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.
