Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490728, here are decompositions:

101 + 33490627 = 33490728
149 + 33490579 = 33490728
181 + 33490547 = 33490728
191 + 33490537 = 33490728
199 + 33490529 = 33490728
251 + 33490477 = 33490728
331 + 33490397 = 33490728
347 + 33490381 = 33490728

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.7.40.

Address: 1.255.7.40
Class: public
IPv4-mapped IPv6: ::ffff:1.255.7.40

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