Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609180, here are decompositions:

41 + 33609139 = 33609180
67 + 33609113 = 33609180
83 + 33609097 = 33609180
103 + 33609077 = 33609180
107 + 33609073 = 33609180
113 + 33609067 = 33609180
149 + 33609031 = 33609180
151 + 33609029 = 33609180

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.213.220.

Address: 2.0.213.220
Class: public
IPv4-mapped IPv6: ::ffff:2.0.213.220

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