Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487396, here are decompositions:

23 + 2147487373 = 2147487396
37 + 2147487359 = 2147487396
53 + 2147487343 = 2147487396
127 + 2147487269 = 2147487396
137 + 2147487259 = 2147487396
149 + 2147487247 = 2147487396
193 + 2147487203 = 2147487396
227 + 2147487169 = 2147487396

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.164.

Address: 128.0.14.164
