Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477290, here are decompositions:

17 + 2147477273 = 2147477290
41 + 2147477249 = 2147477290
53 + 2147477237 = 2147477290
83 + 2147477207 = 2147477290
89 + 2147477201 = 2147477290
131 + 2147477159 = 2147477290
197 + 2147477093 = 2147477290
227 + 2147477063 = 2147477290

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.231.42.

Address: 127.255.231.42
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.231.42
