Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572518, here are decompositions:

29 + 33572489 = 33572518
71 + 33572447 = 33572518
101 + 33572417 = 33572518
137 + 33572381 = 33572518
167 + 33572351 = 33572518
179 + 33572339 = 33572518
281 + 33572237 = 33572518
401 + 33572117 = 33572518

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.70.166.

Address: 2.0.70.166
Class: public
IPv4-mapped IPv6: ::ffff:2.0.70.166

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