Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564720, here are decompositions:

41 + 33564679 = 33564720
43 + 33564677 = 33564720
47 + 33564673 = 33564720
67 + 33564653 = 33564720
89 + 33564631 = 33564720
179 + 33564541 = 33564720
229 + 33564491 = 33564720
257 + 33564463 = 33564720

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.40.48.

Address: 2.0.40.48
Class: public
IPv4-mapped IPv6: ::ffff:2.0.40.48

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