Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500988, here are decompositions:

7 + 2147500981 = 2147500988
79 + 2147500909 = 2147500988
109 + 2147500879 = 2147500988
397 + 2147500591 = 2147500988
691 + 2147500297 = 2147500988
811 + 2147500177 = 2147500988
877 + 2147500111 = 2147500988
907 + 2147500081 = 2147500988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.67.188.

Address: 128.0.67.188
