Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484978, here are decompositions:

17 + 2147484961 = 2147484978
29 + 2147484949 = 2147484978
59 + 2147484919 = 2147484978
101 + 2147484877 = 2147484978
109 + 2147484869 = 2147484978
127 + 2147484851 = 2147484978
157 + 2147484821 = 2147484978
227 + 2147484751 = 2147484978

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.5.50.
