Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542988, here are decompositions:

5 + 33542983 = 33542988
7 + 33542981 = 33542988
137 + 33542851 = 33542988
197 + 33542791 = 33542988
211 + 33542777 = 33542988
229 + 33542759 = 33542988
239 + 33542749 = 33542988
251 + 33542737 = 33542988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.211.76.

Address: 1.255.211.76
Class: public
IPv4-mapped IPv6: ::ffff:1.255.211.76

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