Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525428, here are decompositions:

7 + 31525421 = 31525428
31 + 31525397 = 31525428
61 + 31525367 = 31525428
97 + 31525331 = 31525428
139 + 31525289 = 31525428
149 + 31525279 = 31525428
167 + 31525261 = 31525428
199 + 31525229 = 31525428

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.10.52.

Address: 1.225.10.52
Class: public
IPv4-mapped IPv6: ::ffff:1.225.10.52

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