Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452102, here are decompositions:

5 + 31452097 = 31452102
13 + 31452089 = 31452102
23 + 31452079 = 31452102
41 + 31452061 = 31452102
61 + 31452041 = 31452102
83 + 31452019 = 31452102
89 + 31452013 = 31452102
103 + 31451999 = 31452102

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.235.198.

Address: 1.223.235.198
Class: public
IPv4-mapped IPv6: ::ffff:1.223.235.198

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

Position in π

The digit sequence 31452102 first appears in π at position 677,471 of the decimal expansion (the 677,471ordinal-suffix:st 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.
