Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521394, here are decompositions:

73 + 33521321 = 33521394
157 + 33521237 = 33521394
173 + 33521221 = 33521394
223 + 33521171 = 33521394
307 + 33521087 = 33521394
311 + 33521083 = 33521394
337 + 33521057 = 33521394
373 + 33521021 = 33521394

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.126.242.

Address: 1.255.126.242
Class: public
IPv4-mapped IPv6: ::ffff:1.255.126.242

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