Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479846, here are decompositions:

17 + 31479829 = 31479846
29 + 31479817 = 31479846
43 + 31479803 = 31479846
53 + 31479793 = 31479846
89 + 31479757 = 31479846
103 + 31479743 = 31479846
107 + 31479739 = 31479846
109 + 31479737 = 31479846

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.88.38.

Address: 1.224.88.38
Class: public
IPv4-mapped IPv6: ::ffff:1.224.88.38

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