Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492478, here are decompositions:

31 + 2147492447 = 2147492478
107 + 2147492371 = 2147492478
139 + 2147492339 = 2147492478
149 + 2147492329 = 2147492478
151 + 2147492327 = 2147492478
179 + 2147492299 = 2147492478
181 + 2147492297 = 2147492478
239 + 2147492239 = 2147492478

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.34.126.

Address: 128.0.34.126
Class: public
IPv4-mapped IPv6: ::ffff:128.0.34.126
