Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618100, here are decompositions:

71 + 33618029 = 33618100
101 + 33617999 = 33618100
137 + 33617963 = 33618100
167 + 33617933 = 33618100
179 + 33617921 = 33618100
281 + 33617819 = 33618100
293 + 33617807 = 33618100
353 + 33617747 = 33618100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.248.180.

Address: 2.0.248.180
Class: public
IPv4-mapped IPv6: ::ffff:2.0.248.180

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