Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506856, here are decompositions:

37 + 33506819 = 33506856
59 + 33506797 = 33506856
79 + 33506777 = 33506856
83 + 33506773 = 33506856
167 + 33506689 = 33506856
193 + 33506663 = 33506856
197 + 33506659 = 33506856
233 + 33506623 = 33506856

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.70.40.

Address: 1.255.70.40
Class: public
IPv4-mapped IPv6: ::ffff:1.255.70.40

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