Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521200, here are decompositions:

23 + 33521177 = 33521200
29 + 33521171 = 33521200
59 + 33521141 = 33521200
101 + 33521099 = 33521200
113 + 33521087 = 33521200
179 + 33521021 = 33521200
191 + 33521009 = 33521200
197 + 33521003 = 33521200

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.126.48.

Address: 1.255.126.48
Class: public
IPv4-mapped IPv6: ::ffff:1.255.126.48

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