Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462802, here are decompositions:

31 + 31462771 = 31462802
43 + 31462759 = 31462802
73 + 31462729 = 31462802
79 + 31462723 = 31462802
193 + 31462609 = 31462802
199 + 31462603 = 31462802
211 + 31462591 = 31462802
223 + 31462579 = 31462802

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.21.146.

Address: 1.224.21.146
Class: public
IPv4-mapped IPv6: ::ffff:1.224.21.146

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

Position in π

The digit sequence 31462802 first appears in π at position 86,411 of the decimal expansion (the 86,411ordinal-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.
