Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487506, here are decompositions:

29 + 33487477 = 33487506
83 + 33487423 = 33487506
89 + 33487417 = 33487506
113 + 33487393 = 33487506
163 + 33487343 = 33487506
193 + 33487313 = 33487506
197 + 33487309 = 33487506
229 + 33487277 = 33487506

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.250.146.

Address: 1.254.250.146
Class: public
IPv4-mapped IPv6: ::ffff:1.254.250.146

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