Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521970, here are decompositions:

11 + 33521959 = 33521970
17 + 33521953 = 33521970
37 + 33521933 = 33521970
43 + 33521927 = 33521970
67 + 33521903 = 33521970
107 + 33521863 = 33521970
109 + 33521861 = 33521970
127 + 33521843 = 33521970

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.129.50.

Address: 1.255.129.50
Class: public
IPv4-mapped IPv6: ::ffff:1.255.129.50

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