Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487460, here are decompositions:

11 + 2147487449 = 2147487460
59 + 2147487401 = 2147487460
101 + 2147487359 = 2147487460
191 + 2147487269 = 2147487460
233 + 2147487227 = 2147487460
257 + 2147487203 = 2147487460
347 + 2147487113 = 2147487460
383 + 2147487077 = 2147487460

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.228.
