Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528960, here are decompositions:

7 + 33528953 = 33528960
19 + 33528941 = 33528960
29 + 33528931 = 33528960
131 + 33528829 = 33528960
137 + 33528823 = 33528960
139 + 33528821 = 33528960
163 + 33528797 = 33528960
167 + 33528793 = 33528960

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.156.128.

Address: 1.255.156.128
Class: public
IPv4-mapped IPv6: ::ffff:1.255.156.128

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