Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621172, here are decompositions:

3 + 33621169 = 33621172
23 + 33621149 = 33621172
59 + 33621113 = 33621172
89 + 33621083 = 33621172
173 + 33620999 = 33621172
281 + 33620891 = 33621172
353 + 33620819 = 33621172
359 + 33620813 = 33621172

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.4.180.

Address: 2.1.4.180
Class: public
IPv4-mapped IPv6: ::ffff:2.1.4.180

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