Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472980, here are decompositions:

19 + 33472961 = 33472980
29 + 33472951 = 33472980
43 + 33472937 = 33472980
67 + 33472913 = 33472980
89 + 33472891 = 33472980
131 + 33472849 = 33472980
157 + 33472823 = 33472980
193 + 33472787 = 33472980

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.193.212.

Address: 1.254.193.212
Class: public
IPv4-mapped IPv6: ::ffff:1.254.193.212

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