Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617978, here are decompositions:

7 + 33617971 = 33617978
127 + 33617851 = 33617978
181 + 33617797 = 33617978
211 + 33617767 = 33617978
349 + 33617629 = 33617978
367 + 33617611 = 33617978
379 + 33617599 = 33617978
421 + 33617557 = 33617978

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.248.58.

Address: 2.0.248.58
Class: public
IPv4-mapped IPv6: ::ffff:2.0.248.58

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