Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475726, here are decompositions:

5 + 2147475721 = 2147475726
13 + 2147475713 = 2147475726
73 + 2147475653 = 2147475726
139 + 2147475587 = 2147475726
163 + 2147475563 = 2147475726
167 + 2147475559 = 2147475726
173 + 2147475553 = 2147475726
223 + 2147475503 = 2147475726

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.225.14.

Address: 127.255.225.14
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.225.14
