Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404794, here are decompositions:

23 + 2147404771 = 2147404794
83 + 2147404711 = 2147404794
173 + 2147404621 = 2147404794
193 + 2147404601 = 2147404794
211 + 2147404583 = 2147404794
347 + 2147404447 = 2147404794
401 + 2147404393 = 2147404794
463 + 2147404331 = 2147404794

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.203.250.

Address: 127.254.203.250
