Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456182, here are decompositions:

19 + 31456163 = 31456182
59 + 31456123 = 31456182
61 + 31456121 = 31456182
83 + 31456099 = 31456182
89 + 31456093 = 31456182
103 + 31456079 = 31456182
179 + 31456003 = 31456182
223 + 31455959 = 31456182

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.251.182.

Address: 1.223.251.182
Class: public
IPv4-mapped IPv6: ::ffff:1.223.251.182

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

Position in π

The digit sequence 31456182 first appears in π at position 599,503 of the decimal expansion (the 599,503ordinal-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.
