Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491428, here are decompositions:

11 + 2147491417 = 2147491428
59 + 2147491369 = 2147491428
67 + 2147491361 = 2147491428
79 + 2147491349 = 2147491428
109 + 2147491319 = 2147491428
151 + 2147491277 = 2147491428
167 + 2147491261 = 2147491428
179 + 2147491249 = 2147491428

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.100.

Address: 128.0.30.100
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.100
