Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475498, here are decompositions:

11 + 2147475487 = 2147475498
17 + 2147475481 = 2147475498
59 + 2147475439 = 2147475498
97 + 2147475401 = 2147475498
101 + 2147475397 = 2147475498
131 + 2147475367 = 2147475498
149 + 2147475349 = 2147475498
151 + 2147475347 = 2147475498

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.224.42.

Address: 127.255.224.42
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.224.42
