Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484980, here are decompositions:

19 + 2147484961 = 2147484980
31 + 2147484949 = 2147484980
61 + 2147484919 = 2147484980
103 + 2147484877 = 2147484980
229 + 2147484751 = 2147484980
283 + 2147484697 = 2147484980
367 + 2147484613 = 2147484980
379 + 2147484601 = 2147484980

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.5.52.
