Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521572, here are decompositions:

23 + 33521549 = 33521572
41 + 33521531 = 33521572
89 + 33521483 = 33521572
101 + 33521471 = 33521572
179 + 33521393 = 33521572
251 + 33521321 = 33521572
353 + 33521219 = 33521572
401 + 33521171 = 33521572

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.127.164.

Address: 1.255.127.164
Class: public
IPv4-mapped IPv6: ::ffff:1.255.127.164

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