Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487386, here are decompositions:

43 + 33487343 = 33487386
67 + 33487319 = 33487386
73 + 33487313 = 33487386
109 + 33487277 = 33487386
113 + 33487273 = 33487386
139 + 33487247 = 33487386
167 + 33487219 = 33487386
193 + 33487193 = 33487386

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.250.26.

Address: 1.254.250.26
Class: public
IPv4-mapped IPv6: ::ffff:1.254.250.26

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