Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618168, here are decompositions:

7 + 33618161 = 33618168
19 + 33618149 = 33618168
29 + 33618139 = 33618168
131 + 33618037 = 33618168
137 + 33618031 = 33618168
139 + 33618029 = 33618168
167 + 33618001 = 33618168
197 + 33617971 = 33618168

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.248.248.

Address: 2.0.248.248
Class: public
IPv4-mapped IPv6: ::ffff:2.0.248.248

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