Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484458, here are decompositions:

19 + 2147484439 = 2147484458
109 + 2147484349 = 2147484458
127 + 2147484331 = 2147484458
181 + 2147484277 = 2147484458
199 + 2147484259 = 2147484458
349 + 2147484109 = 2147484458
397 + 2147484061 = 2147484458
421 + 2147484037 = 2147484458

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.3.42.
