Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475440, here are decompositions:

43 + 2147475397 = 2147475440
67 + 2147475373 = 2147475440
73 + 2147475367 = 2147475440
109 + 2147475331 = 2147475440
163 + 2147475277 = 2147475440
211 + 2147475229 = 2147475440
337 + 2147475103 = 2147475440
379 + 2147475061 = 2147475440

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.223.240.

Address: 127.255.223.240
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.223.240
