Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583046, here are decompositions:

13 + 31583033 = 31583046
23 + 31583023 = 31583046
97 + 31582949 = 31583046
109 + 31582937 = 31583046
139 + 31582907 = 31583046
149 + 31582897 = 31583046
199 + 31582847 = 31583046
223 + 31582823 = 31583046

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.235.70.

Address: 1.225.235.70
Class: public
IPv4-mapped IPv6: ::ffff:1.225.235.70

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