Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617172, here are decompositions:

5 + 33617167 = 33617172
13 + 33617159 = 33617172
31 + 33617141 = 33617172
89 + 33617083 = 33617172
101 + 33617071 = 33617172
103 + 33617069 = 33617172
109 + 33617063 = 33617172
151 + 33617021 = 33617172

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.245.20.

Address: 2.0.245.20
Class: public
IPv4-mapped IPv6: ::ffff:2.0.245.20

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