Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473994, here are decompositions:

3 + 31473991 = 31473994
17 + 31473977 = 31473994
23 + 31473971 = 31473994
107 + 31473887 = 31473994
131 + 31473863 = 31473994
401 + 31473593 = 31473994
557 + 31473437 = 31473994
743 + 31473251 = 31473994

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.65.74.

Address: 1.224.65.74
Class: public
IPv4-mapped IPv6: ::ffff:1.224.65.74

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