Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484078, here are decompositions:

17 + 2147484061 = 2147484078
37 + 2147484041 = 2147484078
41 + 2147484037 = 2147484078
71 + 2147484007 = 2147484078
79 + 2147483999 = 2147484078
127 + 2147483951 = 2147484078
149 + 2147483929 = 2147484078
191 + 2147483887 = 2147484078

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.1.174.

Address: 128.0.1.174
Class: public
IPv4-mapped IPv6: ::ffff:128.0.1.174
