Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553980, here are decompositions:

11 + 33553969 = 33553980
13 + 33553967 = 33553980
71 + 33553909 = 33553980
79 + 33553901 = 33553980
101 + 33553879 = 33553980
181 + 33553799 = 33553980
193 + 33553787 = 33553980
211 + 33553769 = 33553980

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.254.60.

Address: 1.255.254.60
Class: public
IPv4-mapped IPv6: ::ffff:1.255.254.60

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