Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482494, here are decompositions:

13 + 2147482481 = 2147482494
127 + 2147482367 = 2147482494
151 + 2147482343 = 2147482494
167 + 2147482327 = 2147482494
257 + 2147482237 = 2147482494
263 + 2147482231 = 2147482494
271 + 2147482223 = 2147482494
373 + 2147482121 = 2147482494

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.251.126.

Address: 127.255.251.126
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.251.126
