Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536682, here are decompositions:

53 + 31536629 = 31536682
131 + 31536551 = 31536682
389 + 31536293 = 31536682
479 + 31536203 = 31536682
521 + 31536161 = 31536682
701 + 31535981 = 31536682
743 + 31535939 = 31536682
773 + 31535909 = 31536682

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.54.42.

Address: 1.225.54.42
Class: public
IPv4-mapped IPv6: ::ffff:1.225.54.42

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