Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501060, here are decompositions:

23 + 31501037 = 31501060
83 + 31500977 = 31501060
113 + 31500947 = 31501060
137 + 31500923 = 31501060
197 + 31500863 = 31501060
251 + 31500809 = 31501060
263 + 31500797 = 31501060
293 + 31500767 = 31501060

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.171.4.

Address: 1.224.171.4
Class: public
IPv4-mapped IPv6: ::ffff:1.224.171.4

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