Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536404, here are decompositions:

7 + 31536397 = 31536404
13 + 31536391 = 31536404
43 + 31536361 = 31536404
181 + 31536223 = 31536404
307 + 31536097 = 31536404
421 + 31535983 = 31536404
457 + 31535947 = 31536404
463 + 31535941 = 31536404

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.53.20.

Address: 1.225.53.20
Class: public
IPv4-mapped IPv6: ::ffff:1.225.53.20

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