Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484140, here are decompositions:

31 + 2147484109 = 2147484140
79 + 2147484061 = 2147484140
97 + 2147484043 = 2147484140
103 + 2147484037 = 2147484140
211 + 2147483929 = 2147484140
271 + 2147483869 = 2147484140
283 + 2147483857 = 2147484140
397 + 2147483743 = 2147484140

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.1.236.
