Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555166, here are decompositions:

3 + 33555163 = 33555166
17 + 33555149 = 33555166
89 + 33555077 = 33555166
173 + 33554993 = 33555166
263 + 33554903 = 33555166
317 + 33554849 = 33555166
467 + 33554699 = 33555166
587 + 33554579 = 33555166

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.2.222.

Address: 2.0.2.222
Class: public
IPv4-mapped IPv6: ::ffff:2.0.2.222

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