Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488460, here are decompositions:

31 + 2147488429 = 2147488460
43 + 2147488417 = 2147488460
79 + 2147488381 = 2147488460
127 + 2147488333 = 2147488460
181 + 2147488279 = 2147488460
211 + 2147488249 = 2147488460
307 + 2147488153 = 2147488460
349 + 2147488111 = 2147488460

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.18.204.
