Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522858, here are decompositions:

11 + 31522847 = 31522858
317 + 31522541 = 31522858
617 + 31522241 = 31522858
677 + 31522181 = 31522858
797 + 31522061 = 31522858
839 + 31522019 = 31522858
881 + 31521977 = 31522858
971 + 31521887 = 31522858

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.0.42.

Address: 1.225.0.42
Class: public
IPv4-mapped IPv6: ::ffff:1.225.0.42

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