Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487452, here are decompositions:

3 + 2147487449 = 2147487452
43 + 2147487409 = 2147487452
79 + 2147487373 = 2147487452
109 + 2147487343 = 2147487452
151 + 2147487301 = 2147487452
193 + 2147487259 = 2147487452
283 + 2147487169 = 2147487452
601 + 2147486851 = 2147487452

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.220.

Address: 128.0.14.220
