Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555580, here are decompositions:

17 + 33555563 = 33555580
53 + 33555527 = 33555580
83 + 33555497 = 33555580
131 + 33555449 = 33555580
197 + 33555383 = 33555580
239 + 33555341 = 33555580
263 + 33555317 = 33555580
293 + 33555287 = 33555580

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.4.124.

Address: 2.0.4.124
Class: public
IPv4-mapped IPv6: ::ffff:2.0.4.124

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