Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581732, here are decompositions:

61 + 33581671 = 33581732
211 + 33581521 = 33581732
241 + 33581491 = 33581732
433 + 33581299 = 33581732
523 + 33581209 = 33581732
601 + 33581131 = 33581732
739 + 33580993 = 33581732
823 + 33580909 = 33581732

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.106.164.

Address: 2.0.106.164
Class: public
IPv4-mapped IPv6: ::ffff:2.0.106.164

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