Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487258, here are decompositions:

11 + 2147487247 = 2147487258
31 + 2147487227 = 2147487258
71 + 2147487187 = 2147487258
89 + 2147487169 = 2147487258
101 + 2147487157 = 2147487258
181 + 2147487077 = 2147487258
199 + 2147487059 = 2147487258
229 + 2147487029 = 2147487258

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.26.

Address: 128.0.14.26
