Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490012, here are decompositions:

43 + 2147489969 = 2147490012
71 + 2147489941 = 2147490012
103 + 2147489909 = 2147490012
113 + 2147489899 = 2147490012
139 + 2147489873 = 2147490012
163 + 2147489849 = 2147490012
191 + 2147489821 = 2147490012
193 + 2147489819 = 2147490012

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.220.

Address: 128.0.24.220
