Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487196, here are decompositions:

83 + 2147487113 = 2147487196
137 + 2147487059 = 2147487196
167 + 2147487029 = 2147487196
227 + 2147486969 = 2147487196
269 + 2147486927 = 2147487196
317 + 2147486879 = 2147487196
347 + 2147486849 = 2147487196
353 + 2147486843 = 2147487196

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.13.220.

Address: 128.0.13.220
Class: public
IPv4-mapped IPv6: ::ffff:128.0.13.220

Public, routable address (assignable to a host on the internet).
