Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462442, here are decompositions:

3 + 31462439 = 31462442
61 + 31462381 = 31462442
79 + 31462363 = 31462442
103 + 31462339 = 31462442
373 + 31462069 = 31462442
421 + 31462021 = 31462442
439 + 31462003 = 31462442
463 + 31461979 = 31462442

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.20.42.

Address: 1.224.20.42
Class: public
IPv4-mapped IPv6: ::ffff:1.224.20.42

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