Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147475760, here are decompositions:

47 + 2147475713 = 2147475760
107 + 2147475653 = 2147475760
167 + 2147475593 = 2147475760
173 + 2147475587 = 2147475760
197 + 2147475563 = 2147475760
239 + 2147475521 = 2147475760
251 + 2147475509 = 2147475760
257 + 2147475503 = 2147475760

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.225.48.

Address: 127.255.225.48
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.225.48
