Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483388, here are decompositions:

139 + 2147483249 = 2147483388
151 + 2147483237 = 2147483388
251 + 2147483137 = 2147483388
311 + 2147483077 = 2147483388
359 + 2147483029 = 2147483388
439 + 2147482949 = 2147483388
467 + 2147482921 = 2147483388
521 + 2147482867 = 2147483388

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.254.252.

Address: 127.255.254.252
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.254.252
