Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487470, here are decompositions:

19 + 2147487451 = 2147487470
61 + 2147487409 = 2147487470
67 + 2147487403 = 2147487470
97 + 2147487373 = 2147487470
127 + 2147487343 = 2147487470
211 + 2147487259 = 2147487470
223 + 2147487247 = 2147487470
283 + 2147487187 = 2147487470

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.238.

Address: 128.0.14.238
