Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607056, here are decompositions:

17 + 31607039 = 31607056
59 + 31606997 = 31607056
83 + 31606973 = 31607056
113 + 31606943 = 31607056
137 + 31606919 = 31607056
227 + 31606829 = 31607056
353 + 31606703 = 31607056
359 + 31606697 = 31607056

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.73.16.

Address: 1.226.73.16
Class: public
IPv4-mapped IPv6: ::ffff:1.226.73.16

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

Position in π

The digit sequence 31607056 first appears in π at position 326,089 of the decimal expansion (the 326,089ordinal-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.
