Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487078, here are decompositions:

19 + 2147487059 = 2147487078
29 + 2147487049 = 2147487078
97 + 2147486981 = 2147487078
109 + 2147486969 = 2147487078
151 + 2147486927 = 2147487078
199 + 2147486879 = 2147487078
227 + 2147486851 = 2147487078
229 + 2147486849 = 2147487078

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.102.

Address: 128.0.13.102
