Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585372, here are decompositions:

31 + 33585341 = 33585372
83 + 33585289 = 33585372
109 + 33585263 = 33585372
131 + 33585241 = 33585372
199 + 33585173 = 33585372
229 + 33585143 = 33585372
239 + 33585133 = 33585372
241 + 33585131 = 33585372

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.120.220.

Address: 2.0.120.220
Class: public
IPv4-mapped IPv6: ::ffff:2.0.120.220

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