Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487180, here are decompositions:

11 + 2147487169 = 2147487180
23 + 2147487157 = 2147487180
67 + 2147487113 = 2147487180
103 + 2147487077 = 2147487180
131 + 2147487049 = 2147487180
151 + 2147487029 = 2147487180
199 + 2147486981 = 2147487180
211 + 2147486969 = 2147487180

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.204.

Address: 128.0.13.204
Class: public
IPv4-mapped IPv6: ::ffff:128.0.13.204
