Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475100, here are decompositions:

53 + 2147475047 = 2147475100
137 + 2147474963 = 2147475100
149 + 2147474951 = 2147475100
179 + 2147474921 = 2147475100
257 + 2147474843 = 2147475100
263 + 2147474837 = 2147475100
269 + 2147474831 = 2147475100
293 + 2147474807 = 2147475100

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.222.156.

Address: 127.255.222.156
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.222.156
