Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473402, here are decompositions:

5 + 31473397 = 31473402
43 + 31473359 = 31473402
71 + 31473331 = 31473402
89 + 31473313 = 31473402
139 + 31473263 = 31473402
151 + 31473251 = 31473402
193 + 31473209 = 31473402
199 + 31473203 = 31473402

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.62.250.

Address: 1.224.62.250
Class: public
IPv4-mapped IPv6: ::ffff:1.224.62.250

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