Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488890, here are decompositions:

23 + 2147488867 = 2147488890
31 + 2147488859 = 2147488890
97 + 2147488793 = 2147488890
139 + 2147488751 = 2147488890
149 + 2147488741 = 2147488890
163 + 2147488727 = 2147488890
199 + 2147488691 = 2147488890
271 + 2147488619 = 2147488890

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.122.

Address: 128.0.20.122
