Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481744, here are decompositions:

71 + 2147481673 = 2147481744
173 + 2147481571 = 2147481744
181 + 2147481563 = 2147481744
257 + 2147481487 = 2147481744
433 + 2147481311 = 2147481744
461 + 2147481283 = 2147481744
571 + 2147481173 = 2147481744
593 + 2147481151 = 2147481744

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.248.144.

Address: 127.255.248.144
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.248.144
