Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506128, here are decompositions:

17 + 33506111 = 33506128
101 + 33506027 = 33506128
167 + 33505961 = 33506128
239 + 33505889 = 33506128
269 + 33505859 = 33506128
281 + 33505847 = 33506128
347 + 33505781 = 33506128
827 + 33505301 = 33506128

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.67.80.

Address: 1.255.67.80
Class: public
IPv4-mapped IPv6: ::ffff:1.255.67.80

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