Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585220, here are decompositions:

47 + 33585173 = 33585220
89 + 33585131 = 33585220
107 + 33585113 = 33585220
257 + 33584963 = 33585220
281 + 33584939 = 33585220
311 + 33584909 = 33585220
359 + 33584861 = 33585220
419 + 33584801 = 33585220

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.120.68.

Address: 2.0.120.68
Class: public
IPv4-mapped IPv6: ::ffff:2.0.120.68

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