Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600962, here are decompositions:

5 + 31600957 = 31600962
79 + 31600883 = 31600962
101 + 31600861 = 31600962
103 + 31600859 = 31600962
139 + 31600823 = 31600962
163 + 31600799 = 31600962
179 + 31600783 = 31600962
191 + 31600771 = 31600962

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.49.66.

Address: 1.226.49.66
Class: public
IPv4-mapped IPv6: ::ffff:1.226.49.66

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

Position in π

The digit sequence 31600962 first appears in π at position 979,443 of the decimal expansion (the 979,443ordinal-suffix:rd 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.
