Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481796, here are decompositions:

3 + 2147481793 = 2147481796
167 + 2147481629 = 2147481796
233 + 2147481563 = 2147481796
443 + 2147481353 = 2147481796
479 + 2147481317 = 2147481796
587 + 2147481209 = 2147481796
617 + 2147481179 = 2147481796
653 + 2147481143 = 2147481796

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.248.196.

Address: 127.255.248.196
Class: loopback
IPv4-mapped IPv6: ::ffff:127.255.248.196
