Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482928, here are decompositions:

7 + 2147482921 = 2147482928
61 + 2147482867 = 2147482928
109 + 2147482819 = 2147482928
127 + 2147482801 = 2147482928
307 + 2147482621 = 2147482928
337 + 2147482591 = 2147482928
421 + 2147482507 = 2147482928
601 + 2147482327 = 2147482928

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.253.48.

Address: 127.255.253.48
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.253.48
