Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487948, here are decompositions:

7 + 2147487941 = 2147487948
17 + 2147487931 = 2147487948
41 + 2147487907 = 2147487948
79 + 2147487869 = 2147487948
131 + 2147487817 = 2147487948
149 + 2147487799 = 2147487948
167 + 2147487781 = 2147487948
191 + 2147487757 = 2147487948

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.204.

Address: 128.0.16.204
