Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497842, here are decompositions:

23 + 33497819 = 33497842
89 + 33497753 = 33497842
233 + 33497609 = 33497842
239 + 33497603 = 33497842
263 + 33497579 = 33497842
281 + 33497561 = 33497842
293 + 33497549 = 33497842
359 + 33497483 = 33497842

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.34.242.

Address: 1.255.34.242
Class: public
IPv4-mapped IPv6: ::ffff:1.255.34.242

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