Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557148, here are decompositions:

5 + 33557143 = 33557148
17 + 33557131 = 33557148
29 + 33557119 = 33557148
47 + 33557101 = 33557148
61 + 33557087 = 33557148
71 + 33557077 = 33557148
101 + 33557047 = 33557148
137 + 33557011 = 33557148

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.10.156.

Address: 2.0.10.156
Class: public
IPv4-mapped IPv6: ::ffff:2.0.10.156

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