Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491452, here are decompositions:

83 + 2147491369 = 2147491452
103 + 2147491349 = 2147491452
109 + 2147491343 = 2147491452
179 + 2147491273 = 2147491452
191 + 2147491261 = 2147491452
229 + 2147491223 = 2147491452
233 + 2147491219 = 2147491452
251 + 2147491201 = 2147491452

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.124.

Address: 128.0.30.124
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.124

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