Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621100, here are decompositions:

17 + 33621083 = 33621100
53 + 33621047 = 33621100
101 + 33620999 = 33621100
173 + 33620927 = 33621100
281 + 33620819 = 33621100
311 + 33620789 = 33621100
419 + 33620681 = 33621100
479 + 33620621 = 33621100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.4.108.

Address: 2.1.4.108
Class: public
IPv4-mapped IPv6: ::ffff:2.1.4.108

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