Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520812, here are decompositions:

11 + 33520801 = 33520812
29 + 33520783 = 33520812
53 + 33520759 = 33520812
103 + 33520709 = 33520812
131 + 33520681 = 33520812
163 + 33520649 = 33520812
191 + 33520621 = 33520812
251 + 33520561 = 33520812

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.124.172.

Address: 1.255.124.172
Class: public
IPv4-mapped IPv6: ::ffff:1.255.124.172

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