Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494362, here are decompositions:

61 + 31494301 = 31494362
271 + 31494091 = 31494362
283 + 31494079 = 31494362
373 + 31493989 = 31494362
379 + 31493983 = 31494362
421 + 31493941 = 31494362
463 + 31493899 = 31494362
541 + 31493821 = 31494362

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.144.218.

Address: 1.224.144.218
Class: public
IPv4-mapped IPv6: ::ffff:1.224.144.218

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

Position in π

The digit sequence 31494362 first appears in π at position 894,486 of the decimal expansion (the 894,486ordinal-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.
